Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Ahoj pali,

I believe something is screwed up.
Either on my device. Or with kp52 modules.
I would like your help on this please.

I have upgraded my device a bit the last days/weeks. And now felt the need to boot stock kernel.
I ended in a few days of reboot loop sessions. Luckily I still have multiboot (I know ;)) and of course use (almost) only u-boot, so I could easily get out of it (most of the times :().

I examined this behaviour and thought it might be my setup (u-boot/multiboot), but I could boot kp47/kp50 and kp52. No problem at all. Only stock kernel oopsed out directly after "sbin/init 2" was called.
I enabled syslog, but to no avail. I could see logs from pk but not stock. I checked modules and depmod and current symlink and everything else. So I ran out of ideas...
Then I checked some more logs I never noticed before :rolleyes: in /var/log.
maemo-optify-boottime
oopslogtail

The oops one brought me to the idea to check mtd2 with sp-oops-extract and I found some strange messages:
Exactly that module I had in suspicion a few hours ago, as it was strange that after installing kp52-modules, I did not have that "#fixed by power-kernel" line in /etc/modprobe.d/bridgedriver.
So I reinstalled modules and then it looked exactly like expected.
Before (and after first module install: After second module reinstall: After manual echoing the version (in postrm): Only with the last entry, the stock kernel boots up.

It was no difference if booted with u-boot or kernel from NAND directly.

Can someone confirm that stock kernel does not boot with latest u-boot and kp52 modules?
Or is it something strange on my device?

One more possible reason: I needed to use backupmenu (for the very first time) a few days ago (dumb me upgrading) and had some problems to restore, claiming something about corrupt fs. But single restore, first root - then opt, worked and kp52 works flawlessly.
But I have those strange boot-maemo-optify logs and messages like
But /home has enough free space and is working okay. I am afraid to use e2fsck on /home, as it ruined my debian image a few times already.


So enough now, what do you think?
Might it be some bug? Or why bridgedriver did not get updated on first install? And why stock kernel only wants to boot with original entry?

Thank you in advance for your help and/or experienced tips.

P.S.: oh and btw if this tends to be something strange only on my device I will create new thread ...

check voltages , read overclocking/underclocking tutorial

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

@freemangordon: can you look at @peterleinchen problem?

If I remember correctly kp52 has updated dsp bridge kernel module which needs new options in /etc/modprobe.d/bridgedriver. So maybe it can break stock kernel, but I did not have this problem. I can boot both kernel-power and stock kernel (with updated modprobe.d). But this could be device dependent...

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

It is like that for as long as we have harmattan bridgedriver backported in KP - KP48 iirc.

This is what I have on my device(kernel-cssu):
not specifying shm_size is needed so both kernels to coexist and to use their defaults (0x500000 for KP and 0x400000 for omap1)

No idea who changed that and why, but I don't think it is KP:

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

@pali and fmg
Thanks, sounds reasonable. As I have some other strange behaviours (USB does not get recognized, but I need to unload g_file_storage once manually) and now this and those strange optfs too low messages, I decoded to start all over with a backup from July and upgrade one more time.
One beg: does anybody have the mkfs command for optfs? I am gonna clean optfs on rescue shell and then restore backup. Or is it just a plain mkfs? Thinking about some root reserved clusters, naming and so on ...

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

AFAIK no reserved things - just make sure you ID partition correctly, as plain fdisk does something funny with it (like setting same ID for every type of partition).

Not so long ago, I had a headache trying to understand why N900 fails to properly use perfectly fine partition table, in particular, deny to use OptFS. It turned out, that some startup scripts (rcS-late?) "cleverly" identify partition meant to be Opt by... checking ID. That is, f****n ID - almost as stupid, as using labels for that purpose. As every partition has same ID, it wanted to use MyDocs (as first found partition with matching ID) for OptFS purposes, resulting in disaster. Setting correct Ids via sfdisk (without re-formatting, just changing IDs itself) fixed it immediately.

Other than that, no special requirements for OptFS, you may give it whatever labels, root reserved percentage, journals, etc. you feel fancy.

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Annoying, isn't it? I don't understand this world's obsession with IDs. What's wrong with good old /dev/[hs]da[1234]? However hard I try, I can't think of a use case when an ID would be preferable. Quite the opposite in fact, I've lost count of how many times it got in the way of doing things (resizing partitions, for example).

I see it as an annoying penetration of the Windows way of thinking into the open-source ecosystem and a contamination of the latter with the former.

Sorry about the rant, couldn't help it.

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

<OT>
Well, I can give you a few reasons:
- I know lots of people who are unable to insert RAID disks in the correct order
- the use of multiple external disks for backups, where certain locations need backup to certain disks

But none n900 or embedded-related.

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Just a short feedback: of course I stumbled again into some troubles (see 720p thread and other posts of mine from today :)).
But after formatting optfs (yes, it was somehow corrupted) and upgrading once more and solving the trouble, it looks like everything is fine.
Thanks again for fast feedback.

Voted! :)

debug modules are still only v50 in testing...

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Somehow you voted twice ;)

Going to promote debug modules

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Yep, as it is such useful package :D
Idk how it could happen, but it is not the first time. Happened also last week. But then I accidentally pushed the thumb twice. This time it looked like I pushed thumb down, and then of course I pushed once the thumb up. Resulted in two postive votes ...

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

I saw similar situations in the past a few times. It happened to me once, too (I voted twice for the same package), but that was 2-3 years ago. This is offtopic, but wanted to report here, as it may mean there are some issues with package voting system. BTW, is there a thread with voting/promotion issues? Could http://talk.maemo.org/showthread.php?t=37125 be used to discuss such issues?

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Anyone else having problem updating to v52 for "boot image for U-Boot" package using the application manager (HAM)? I'm trying to upgrade from v51r1 to v52 but can't due to a conflict (no details available) with the "settings and overclock" package. Don't know if it would work to uninstall the "settings and overclock" package, update to v52 and then try reinstall the settings package.

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

@sowwhatyoureap: you can without problem uninstall "settings & overclock" package and then install it again. If you have still problems try to update kernel via apt

Dear sowwhatyoureap,

Yes I have the same problem. Please try to see if it is the same that I reported in this message of the thread:

If it is the same problem, you have a workaround here:

Please let us know, because in the case we should ask pali to manage for a solution.

Thanks for your feedback.

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

Ok thanks, it seems to have worked -- uninstalled the settings package, updated kernel-power-bootimg to v52 successfully and then reinstalled settings package. However, during reinstallation of kernel-power-settings, I noticed it has a depedency on the kernel-power package (via , but gave it a go hoping it wouldn't autoflash the kernel over U-Boot. It came to the confirmation message to flash the kernel, but I canceled the dialog (clicking the "blurred area" above) causing it to show a message that the installation failed.

Despite this, it seems to have managed to install the relevant parts of kernel-power-settings as I'm able to run kernel-config properly. It shows up in the uninstall section of HAM as well.

I'm not really sure what the conflict was that caused the update to complain -- HAM just said "conflict" sadly -- so I can't really confirm that it's the same issue that you linked. Didn't mess around with apt-get as the reinstallation of kernel-power-settings via HAM was sufficiently successful (see above). It may however be related to a dependency issue with kernel-power (via kernel-feature-overclock or kernel-feature-smartreflex?) as mentioned above.

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

I've been followin up on this, and found it has been raised 8 time by different users, though I don't know if there's someone already using it. I can't advice on the modules Pali as I have no experiece on them. here was a post on the request,

It'd be a great feature esp over wifi/usb as I think the missing connection is tha app to run it (which is already available for Windows, Linux and Symbian)

yeah

Re: [Announce] kernel-power stable v52 in Extras-Devel
 

You could show your current status of the installation with the following command:

Then You could easily reveal if it is a dependency problem just with this simple command:

This command is safe since the -s option tells apt-get to only simulate the upgrade, so that it only shows what should have to be done. Then give us feed back about the output...

Alright, here's my output from dpkg -l kernel*:

and here's from the simulated (didn't know you could do that, thx :-) ) apt-get upgrade:

This would suggest that the dependency problem lies with smartreflex, I assume?

Re: [Announce] kernel-power stable v52 in Extras
 

Run as root:
$ apt-get install kernel-power-flasher

Re: [Announce] kernel-power stable v52 in Extras
 

@sowwhatyoureap: AFAIK, from my point of view yes, there is a dependency problem, the same I mentioned before.

One question: are You trying to run the power kernel from U-boot or are You going to install it as a unique kernel in Your system?

If the answer was yes, i.e. You are going to launch the kernel power throughout U-boot, then two questions would rise into my mind for pali:

@pali: if one wants to use the kernel power throughout U-boot, is it necessary to install kernel-power-flasher? I am asking that because I (probably erroneously) think that kernel-power-flasher will ask to flash the kernel power into the nand, to substitute the Nokia stock kernel.
And in general, question number two, which is the minimum set of packages needed for this kind of configuration? I'm gonna try to guess, and please, let me know where I am wrong:

* kernel: yes because it is needed by U-boot?
* kernel-bootimg: no because U-boot is launched into this kernel "session"
* kernel-flasher: yes but it is substituted by u-boot-flasher, and it can be removed if U-boot has to remain installed
* kernel-modules: yes
* u-boot-flasher: ??? needed for installing U-boot; would it be possible to remove i after flash?
* u-boot-for-power-kernel: not necessary, obsolete package?
* u-boot-tools: yes
* uboot-mkimage: not necessary, obsolete package?
* uboot-power: not necessary, obsolete package?
* uboot-pr13: not necessary, obsolete package?
* kernel-power: not needed?
* kernel-power-bootimg: yes, needed by U-boot to launch the kernel power
* kernel-power-flasher: no if one use U-boot?
* kernel-power-modules: yes

Thanks in advance.

Re: [Announce] kernel-power stable v52 in Extras
 

Yes kernel-power-flasher is needed. But if you have u-boot already installed, kernel-power-flasher will ask you if you want to flash kernel power into nand or not.

All these packages are needed for stock kernel. And because u-boot has attached stock kernel, all those packages must be installed.

This is optional package, contains bootimg of stock kernel. It was used to create uboot combined image (uboot+kernel)

Both packages must be installed if you want u-boot.

All these packages are really obsolated and should not be installed (conflicts with u-boot-flasher).

All these packages must be installed if you want kernel-power in device (both u-boot or flashable version)

This package is needed if you want to boot kernel-power from u-boot

Re: [Announce] kernel-power stable v52 in Extras
 

@pali: thanks for Your answer, however I am wondering why HAM (or FAM or apt-get) got stuck in a unconfigured situation like the one described by sowwhatyoureap.

I mean: after his first tentative, he was not able to install the new kernel (KP52), and then, after Your suggestion, the installation process with HAM was not able to automatically complete the configuration of kernel-power-settings, because kernel-power-flasher was missing, and apt was not able to recognize that kernel-power-flasher had to be installed too.

In my case, a similar situation arose when I moved from multiboot and KP 51r2 to U-boot and KP 52: the fact that kernel-power-bootimg does not provide any more all the KP features leaded me in the same situation: I coudn't install kernel-power-settings. At present, I managed the situation as reported in

http://talk.maemo.org/showthread.php...79#post1354279

and precisely I do not have kernel-power-flasher installed, and I continuously reboot changing from KP and stock kernel, without big problems (sometimes, when i boot with KP, I need to retry 2 or 3 times before the KP starts).

In any case, it seems that the dependency declared into the control files of the KP and kernel-power-settings packages are not sufficient to let apt-get or Ham to automatically complete the process.

What do You think about it? And if You agree, could we re-think the structure of the dependencies?

Thanks in advance.

Re: [Announce] kernel-power stable v52 in Extras
 

I cannot add features back to -bootimg package because it breaking new clean installation of kernel power (search threads for more info). HAM and FAM are broken by design.

But you can fix it by installing kernel-power-flasher package (Linux kernel for power user) via HAM too.

See installation instructions again from first post.

Re: [Announce] kernel-power stable v52 in Extras
 

Yesterday i flashed n900 n installed cssu-testing and cssu-thumb.
And back in the day i used to install power kernel after these 2 but this time i noticed that there was a power kernel
for cssu (thumb version) in the packages too. So im confused , what to install? Power kernel or power kernel for
cssu(thumb).

Re: [Announce] kernel-power stable v52 in Extras
 

You know about a kernel I have never heard of. There is just kernel-power AFAIK and no thumb version. K-P52 has the thumb2 patch applied so that apps in the thumb repo work.

Re: [Announce] kernel-power stable v52 in Extras
 

There is also a package called
Linux Kernel for Community SSU(boot image for uboot and multiboot)
just like Linux kernel for power user(boot image for uboot) in the application manager.

Re: [Announce] kernel-power stable v52 in Extras
 

I think this might be the something-something-cssu3 kernel, the one that is partially based on older release of kp, but with less features (mainly overclocking and thumb2 patches)... I think it was created as a very early preparation stage for future possible kernel updates via CSSU. Either way, go for power kernel, it's newer, better, has more stuff compiled in and if you used kernel power before, it'll better suit your use cases ;)

Re: [Announce] kernel-power stable v52 in Extras
 

ok then i will install linux kernel for power user. i dont know anything about cssu kernel.

Re: [Announce] kernel-power stable v52 in Extras
 

i have posted this in a similar thread but no reply. am new to the community and its actually my first post here. (1) i messed up my phone so i reflashed, 2) updated to T8.2 (3) following a guide here, i installed (with FAM), u-boot with kernel 2.6.28-omap1; linux kernel for power user v52; linux kernel for power user boot image for u-boot; linux kernel for power user settings and overclock (4) type in xterm: u-boot-update-bootmenu (5) restarted the phone and slide out keyboard, u-boot came up, but after selecting power kernel in bootmenu, it said 'starrting kernel' and after sometime phone went off.

So pls i need a simple step by step guide on how to make u-boot work with power kernel v52, and nitdroid,

Am tired of flashing the kernel as after following some guide and installing power kernel and u-boot, either my phone doesn't boot again or will boot straight to power kernel without u-boot.

Re: [Announce] kernel-power stable v52 in Extras
 

What will contain kp53? Any to do list?

Re: [Announce] kernel-power stable v52 in Extras
 

Did you install anything except packages you already mentioned? I'm almost sure that the actions you are talking about are being done by a lot of users often without any problems. I've done it myself three times. So If there is really some problem it will cause a lot of complaints soon. And if there are no problems with the packages I suggest you re-check all your actions. Maybe try installing everything from command-line instead of FAM.

Re: [Announce] kernel-power stable v52 in Extras
 

@int_ua
what of changing zimage to uimage? creating item file u-boot, and copying uimage to somewhere? are this steps not important with u-boot? pls i really need a guide from the scratch

Re: [Announce] kernel-power stable v52 in Extras
