Re: [Announce] kernel-power v47
 

After replacing the battery, the battery widget and conky still show the previous battery level.....
How to solve or reset it?

Re: [Announce] kernel-power v47
 

Thank you Mentalist Traceur. I have to take closer look at this (after I come back from Peru month from now). I think I have required knowledge how to do it - thanks to http://al.robotfuzz.com/~al/maemo/u-boot/. Anyway It would be nice to have package in extra-devel with uboot: PK+nokia default kernel, or at least uboot package (those uboot-pr13 packages somehow don't work). Another thing came to mind, does anybody tried kexec to boot from nokia default kernel to PK ?

Re: [Announce] kernel-power v47
 

I dont get how to dualboot with meego.
he says use uboot but u cannot install uboot with powerkernelv47 :/

Re: [Announce] kernel-power v47
 

usually n900 to pc transfer speed is about 15mb/s but after i use h-e-n with any usb drive the transfer speed between n900 and the pc (with a usb cable) goes down to 3mb/s

so : is this normal or is it casued by kernel-power v47?

please someone confirm

Re: [Announce] kernel-power v47
 

Pillum, it's because that version of uboot has explicit dependency on KP46, so you can't have uboot with KP47. The sad thing is that required KP46 is not present in extras-devel anymore, so you can't have uboot at all.

Re: [Announce] kernel-power v47
 

so atm, you cant use MeeGo with v47? :(

Re: [Announce] kernel-power v47
 

No, you can still have u-boot (and by extension MeeGo) with Power47, you just have to be willing to read directions a little and do some work, instead of just clicking on a link in the app managers.

As for the above kexec question... Pali tried to see if he could get kexec to launch other kernels from within the console you can get now at boot with power47, but I don't believe it ever ended up working for him.

Re: [Announce] kernel-power v47
 

hello can some one tell me anything about my problem i have posted above

Re: [Announce] kernel-power v47
 

I decided to give the new version of power kernel a go (it's been about a year since i tried and then later removed it due to instability) and have a few comments:
-there's definitely a noticeable and pleasant improvement in the UI here and there for things i do regularly (running ideal with max 750) so it stays inside the original power envelope at all times).
-i haven't yet seen the instability in modrana that i encountered last time. Too early to say for sure yet but i'm hopeful. :)
-the "reboot" command now only shuts down, which is annoying. I seem to remember seeing this was a known bug and it didn't do it with the vanilla kernel.
-this package should be made to conflict with the old fcam-driver version that it is incompatible with so as to avoid destroying camera function: http://talk.maemo.org/showthread.php?t=39091. apt-get install fcam-driver (bringing my installed version to the latest) fixed the problem but i missed a few photo opportunities today when all camera apps failed to work, and also had a need for the flashlight, which also wouldn't work.

Thanks for picking up the standard and moving forward with it, pali.

Re: [Announce] kernel-power v47
 

I hope you triple-checked that it is not faulty charging cable issue? I repaired it twice, then, when it was damaged third time re-soldered it to completely different design (i talk about stock N900 wall charger) and problems perished.

I ask, cause Your problem seems to be totally unrelated with kernel-power, but of course i don't know for sure. Please, check that, and if its unrelated with kernel, report it back.

If reinstalling fcam-drivers solve the issue, package shouldn't be marked as conflicting, cause in this case, we couldn't reinstall fcam-drivers, without incompatibility messages forcing us to uninstall kernel-power (and, probably, bricking our device), and so goes on...

Or i miss something?

Re: [Announce] kernel-power v47
 

Do you have advanced power installed? I had that happen with that package.

Re: [Announce] kernel-power v47
 

Hello There i have a problem with h-e-n after using it with usb flash
the transfer speed between n900 and the pc goes down from 15mb/s to 4mb/s
but if i rebooted my n900 the speed between n900 and pc goes again to 15mb/s
and if i used h-e-n the speed goes back to 4 mb/s any solutions
is it a problem with kernel power v47 or with h-e-n please somebody confirm

Re: [Announce] kernel-power v47
 

yeah, battery drains at v47 as mad. But it feels snappy all the time. (even w/o oc)
And with v46 i had several issues f.e. with bluetooth that seems to be less with v47.

I like v47 very much:)

Re: [Announce] kernel-power v47
 

oh, holy crap, that is the one i looked for for a long time. And now it doesnt work with v47...
But thanXXX - i will observe that project::)

Re: [Announce] kernel-power v47
 

I don't have advanced-power.

Re: [Announce] kernel-power v47
 

Karam - please stop spamming every single thread with your questions about HEN an PC suite mode. You asked it before here - no need to re-ask. You asked it also in both HEN topics. It seems that only You're affected by such a flaw, so try finding solutions Yourself. Or provide HEN maintainers by more debug data about Your setup - cause You're only one experiencing this kind of problems, its highly possible that it's due You other packages/tweaks installed.

Teohhanhui, you didn't asked my question about You problem - how do you think answering only for last-page questions can help us to help You? ;)

Re: [Announce] kernel-power v47
 

I am going to look into seeing if I can patch in a menu to u-boot. but the problem is that the ones I've found are valid to u-boot v2; I just don't agree with multiboot and its flashing the kernel partition over and over. However, the instructions and links found on the forum (i.e. Matan's u-boot and building the one found here) produces a u-boot which does not work (it freezes on 'Starting kernel') on HW revision 2204, amongst others (I found this out the hard way after Nokia Care replaced my original 2101 with a 2204). The uboot-pr13 in the repositories does work, but then you lose the added extras and it has the stock kernel included rather than power. However I've patched in all of the changes to the source of uboot-pr13 (which Stskeeps kindly provided to me) and will host this shortly for anyone to work on, should they so wish ;)

Re: [Announce] kernel-power v47
 

Looking forward to that Tigerite! :D

Re: [Announce] kernel-power v47
 

Sorry. Didn't get the notification for some reasons.
Anyway, I don't have any technical background in electronics/electrical components so there's no way for me to know if something's broken unless it stops working... :p
I will report back if it happens again.

Re: [Announce] kernel-power v47
 

What you missed is that i said it should be marked incompatible with the older (i.e. incompatible) version of fcam-drivers. It's better to prevent an installation if it breaks basic systems. Then people would know to look for a solution before their camera is broken (i.e. update drivers) rather than be stuck with a nasty surprise.


I haven't timed anything but my battery really does seem to drain faster now (or at least the battery indicator decreases faster). Has anyone used batteryeye to quantify this?

Re: [Announce] kernel-power v47
 

Just try to use USB cable to charge from PC ;) We want to check if bme show proper behavior, that way it shouldn't matter if You're charging from wall charger (data pins crossed) or USB. Unless we meet some strange bug with only fast-rate charge (enabled by mentioned earlier cross between D+/D- pin) - but i really doubt about that.

Flandry - this way You're right, of course. But please, don't do measurements (and don't recommend others to) of battery drain by using battery-eye. Battery-eye, using standard bme guessing methods, just... Well, guess - when we talk about battery charge percentage. Only info that may be useful from applications like that is Voltage - mAh, percentage of charge etc are just estimated values.

Even worse, this like to turn into total mess when You switch heavy/low usuage many times during one cycle, then, on another - for example - use only low use or only high use. For me, Battery-eye show under-zero capacity 1-2 hours before real discharge almost 100% times. Not to mention how it goes crazy when You replace battery with new one, or - scary word - hotswap it ;)

Only one exception from that may be dr_frost mAH graph, tied strictly with voltage - but even voltage can fluctuate highly on power-cycle (yea, after turning off/on you can have higher voltage for even quite long time), so measurement by that way can show You that powercycle charge Your battery :p On the other hand, programs like battery-eye use some build-in artificial handling of powercycles - when you do it, it mandatory shows huge capacity drop, so, as i mentioned in other thread, You can do 50 power cycles, then use Your N900 for another day with -70 capacity all the time ;)

Re: [Announce] kernel-power v47
 

After having this issue for several days it suddenly disappeared:rolleyes:
Audio is transmitted just fine to and from carkit via bluetooth again. I have no clue what might have caused the issue as I didn`t change anything in the meantime:confused:
I can also confirm that kernel v47 works with bluetooth headset HS-56W.
So for me kernel v47 seems to have no issues with bluetooth for me...
Sorry for the confusion caused by this!

Re: [Announce] kernel-power v47
 

Thats important info, but are You sure that absolutely nothing changed on your N900, i.e no updates etc? That would be really strange, if happen out of nothing.

Re: [Announce] kernel-power v47
 

Yeah, at least no system or bluetooth relevant updates or changes...
I´ll keep an eye on this, but to me it seems just like a strange one-time event

Re: [Announce] kernel-power v47
 

I am dealing with SW development for at least 20 years and trust me, there is no such thing like "strange one-time event". There are reasons why you have had a problem and there are reasons why you don't have it anymore. Just do you best to find them (if possible), it will help a lot.

Re: [Announce] kernel-power v47
 

i would like to install kernel v47 BUT will i be-able to keep my packet injection kernel (2. Power46-wl1) ? these are my custom kernels.

1. Stock Maemo
2. Power46-wl1
3. Power46
4. n12 umay
5. Backupmenu

Re: [Announce] kernel-power v47
 

Well, the very day I posted here about my problem with the carkit I verified with my old bluetooth headset which worked right away. In between I received/installed an update for MIR Translator, not other changes.
This day I also asked in the thread regarding obex with PBAP support if someone else is having the same issue. HSchmitt answered that obexd can´t be the cause as audio transmission via bluetooth is done by bluez.
Over the weekend I updated and installed a few more apps but none of those is bluetooth related: Khweeteur, cutetube QML, Ytube, TweetSuite, appwatch, shaketowake2, Marble, eSpeak, witter and ZapLoc.
Hm, might be that I also played a bit with overclocking and undervolting during the days in question, but was only using stable configs...
As I said, will keep an eye on that and keep you guys updated...

Re: [Announce] kernel-power v47
 

Ok, for completeness, I installed v47 on March 3rd.
By checking my call history I can confirm that my carkit worked fine until end of April using v46.
One unusual thing I did today was disabling/enabling bluetooth accidentally using bluezwitch. Normally I just leave bluetooth enabled all the time.
I think, but am not 100% sure, that I rebooted the phone while I had the problem which would be like the same as re-enabling...

Re: [Announce] kernel-power v47
 

You are right about the music being fixed but you wont be able to change your alarm ringtone until another fix is made. Using newest version and I get 'internal error. Application clock closed.'

Re: [Announce] kernel-power v47
 

Hi PowerKernel47 devs,

thanks for all your work. I have been really pleased with many aspects of this kernel.

However, I was wondering if you acknowledge that there could be a problem with battery lfe on this version. I left my phone on standby overnight and it dropped from 8 to 5 bars with almost nil CPU activity.

Now it's possible that v47 is not to blame, but the problem seemed to start at the time I installed it.

Do any of the v47 devs notice a difference, and has there been any investigation?

Cheers, X.

Re: [Announce] kernel-power v47
 

Mine did same for first few days / reboots. Rock solid and eating far less battery now. Reboot it and test until it improves, report back if not.

Re: [Announce] kernel-power v47
 

Its rather striking that so many users experience a little instableness and battery drain the first few days, but after that the phone seems to have adapted and everything comes back to normal.

I still think the battery drains slightly faster but I cannot prove that because I have not made exact measurements. Still very happy with this new kernel, my phone is also a little 'snappier', and I am willing to offer a little battery life for instant response.

Keep up the good work.

For the record:
N900 - Maemo 5 PR1.3
Latest CSSU (20.2010.36-2maemo14.1)
Power Kernel v47
Undervolted: LV-profile
Overclocked: min 250, max 805
SmartReflex: VDD1=1 VDD2=1
HWsync: enabled
using extras-devel

Re: [Announce] kernel-power v47
 

Powertop, top, batterygraph, ps logs or it didn't happen.

Re: [Announce] kernel-power v47
 

For what is worth.. since I updated from v46 to v47 I haven't noticed any difference in speed OR in battery consumption (using the same OC settings: LV and 250-850).

In fact, I seriously doubt that a patch here or a patch there (of the kind we're talking about) can provide any of those two effects in any significant manner.

For people reporting these things, as *vi_* has asked, please try to provide further information (e.g. what exactly you did besides updating the kernel) and any logs that may be relevant..

Re: [Announce] kernel-power v47
 

I have high drain with 46 and latest CSSSU. I keep seeing stuff eating CPU that should be silent, like status menu, dbus daemon and the like. How many of you have CSSU in?

Re: [Announce] kernel-power v47
 

I wouldn’t be quick at judging against kp v47 or CSSU or their combination for battery drain. I mean would it not affect everyone? I have this configuration for many days now and I have not experienced any unusual battery drain either idle or when using it.
This is my battery drain for about ten hours of inactivity at night; just gsm, almost perfect is it not?

Re: [Announce] kernel-power v47
 

wow !! thats really good !

Re: [Announce] kernel-power v47
 

May I ask a question to all of those having battery drain problem with v47 ?

What is the result of this command please ? (open a terminal window) :

A++
