Re: [Announce] kernel-power stable v50 in Extras-Devel

(SOLVED):D
Thnx to retsaw, the problem was solved.
The problem occurred because I was rebooting the device while the hardware keyboard was closed.

Code:

Hello guys

1-Two days ago I downloaded KP50 using HAM, but didn't install its boot image. (then rebooted)



2-After that I downloaded Multiboot + maemo-kernel-image using :



        Code:


        
apt-get install Multiboot-kernel-maemo


3-then while the device is booting multiboot interface showed me that I have only one option to choose which is (maemo default kernel image.) So I chose it and everything were fine.



4-I wanted to use KP50 so I installed its image using :



        Code:


        
apt-get install kernel-power-bootimg


Then when I rebooted multiboot interface did not start at all this time. The device directly booted into desktops. 

In Conky it shows that I am using maemo default kernel.

-what to do? how to switch to KP50 image ?

Any idea plz?

sorry nope.
one thing I can be sure it covers very specific use scenario.
the videos used to work on KP 49. After updating to KP50 my device come in weird state. after one or two reboots the state vanished, so i couldn't reproduce it anymore. (it started to work properly as my device was in usual state).

I know that some uses of player triggered bugs in this state while other were perfectly okay. As MediaBox is only a wrapper and it uses backends from another players, I believe the difference was a backend, since codecs used for both videos triggered different backends (Mediabox basing on config and media type can choose backend automatically).

Videos was just some people playing the instrument on youtube. The videos were directly downloaded from youtube (using a pc browser) and no changes were done since then. (the videos are SD quality but not scaled for the device). I even have two videos with same contents but one a flv and one an MP4 I believe (different copies from youtube server of same video). As formats were different and I mostly remember my config I'm sure one of triggered MAFW backend and the another triggered MPLAYER backend. But since the state which was able to trigger a bug was temporal, after rebooting I couldn't reproduce anymore (the baddie was reseted to something more rational). I may try to reproduce the same enviroment but even then I may fail to reproduce.

So I'm useless to help, until someone trigger the same.

Re: [Announce] kernel-power stable v50 in Extras-Devel

well, for some strange reason it seems it is better to do a full power-cycle after kernel reflash, I have some problems if doing a simple reboot with older kernels too.

It works, you just need to have updated drivers... Use the search, I am sure you can find it!

Re: [Announce] kernel-power stable v50 in Extras-Testing

@freemangordon
So general problem is known and old: flashing kernel make battery machinery unstable until battery is physically reset (full charging cycle), and during that unstability weirdest bugs happen. On other side having to do full battery reset once reflash is small payoff for ability to use both VDD properly (you did it - nokia failed).

@pali
Funny - you did your best to make people find it - it's in first post. Still people happens to be unable to find it. However N900 is for geeks, even a geek can be dumb for a while (no offence to arnoldux personally).

1. Switch off your N900 by means of actuating the mechanical bi-position power disruption dual location mechanical button switch.
2. Unplug the rear side battery holding compartment recess cover.
3. Dislocate the lithium-ion electro-chemical potential electrical energy holding cell from the recessed battery location birth.
4. Immediately after creating an electrical non potential between the chemical electrolyte capacity of the bl-5j cell, Insert the pre-charged battery cell into the now prostate N900 and impregnate it with chemical energy in order that it may live

GIVE IT LIFE.

4. Turn on your N900.

Did anyone had these issues same as mine?

i tried to reduce resolution to DVD quality, the stutter is still there even though a little less than with 720p.

Anyone able to help solving this?

Reboot bug still there... Edit: Unless if it was plugged on wall charger or USB on reboot.
:confused:

Just curious: could someone take a look at this voltages and tell me if it's everythig ok? I mean, how could higher speeds uses lower voltage ? I'm sure its a dumb question but i couldn't resist. :D

Re: [Announce] kernel-power stable v50 in Extras-Testing

@vi_

sure but guys like me with only one batterry have to recharge it to max, or perhaps even full recharge cycle (to min and back to max). It's annoying but acceptable since people do not reflash kernel each 2 weeks, and your kernel is already much better than nokia's one.

So I already said the small anoyance once month or two is tiny payoff for having your kernel which have so many shiny abilities which nokias one doesn't have and at once have most current version. Yeah sure I will not use every ability once a month, but you already done VDD1 and VDD2 working (even for overclock) which makes device use batterry less which is everyday profit from using your version of kernel.

Cheers pali, freemangordon and your team!

Re: [Announce] kernel-power stable v50 in Extras-Testing

Is it not working at all, or just taking a very long time to get a fix? If you use network positioning you might want to change the server from Nokia's supl.nokia.com to Google's supl.google.com, one of my N900s takes ages to get a fix using Nokia's server while for some reason the other only takes a minute or two, until I switched to using Google's servers, which seems to enable both N900s to get a GPS fix quickly.

Hi Everyone,

I'm not sure if this is a KP problem (happened when I upgraded KP), but I can't get ussd commands to work from the phone app anymore although it used to. I have ussd common installed along with KP50 & latest CSSU 3.1. So basically #220* for example doesn't work anymore on the phone application & gives "No celluar connection available".

Let's debug :D

Yesterday I decided to disable ramzswap module, I just renamed file /lib/modules/.../ramzwap.ko. Phone became so fast...
Why is it enabled by default?

Re: [Announce] kernel-power stable v50 in Extras-Testing

Why? cat /proc/swaps - I saw ramzwap before disabling.
I didn't enabled it explicitly.
I have installed compcache-tools, nothing more I did.

Then go find who had enabled it and where ramzswap is insmoded, as definitely it is NOT kernel-power (or any other of *-power-* packages) enabling ramzswap by default.

I know, I just couldn't do it other way.
Maybe because something insmods it explicitly.

ramzswap is initialized just in the middle of startup process:

please post at it's dedicated thread
for you question : *SO YOU DON'T BUG OTHER THREADS*
check this

however later versions are even better
the dev finally gave up 125mhz in underclock and used 500mhz in overclock profile.
i can say it's now very good application

Seems it was kp49. I was waiting for cleven to support kp50. Now with kp50 the hacked fmtxd works fine again. The problem I had (fmtxd not being able to change power level) is also mentioned in first post of kp49 thread. No more trouble with 50.

Re: [Announce] kernel-power stable v50 in Extras-Testing

I apologize for the length of this post, I just had to post my appreciation of this amazing piece of work.

I upgraded 9 days ago from KP49 after reading through many dozens of posts to make sure I wouldn't run into any problems.
I'm not using the FM transmitter boost program, nor am I (currently) using any of the boot menus available or any battery patches or other such tweaks, so I went for it - and I couldn't be happier with my N900!
The upgrade could not have been easier, and the difference in smoothness is staggering!
Seriously, a kernel change should not make this much of a difference! :)
Of course, I'm running CSSU Testing (21.2011.38-1Tmaemo3.1), so I'm sure that plays a huge part too... likely the difference I'm seeing is due to the combination of the two.
That said, the difference wasn't truly noticeable until KP50.

I've noticed a reduction in battery usage, though I haven't measured anything so I can't provide hard numbers.
Another thing I noticed is the swap usage is considerably less over time than I previously had.
I've always noticed that when my N900 was lagging badly (like when trying to answer it when ringing), I was well over 200MB into swap. It seems 210MB is the magic point where it is downright painful (and embarrassing) to use.
I do tend to abuse it by leaving too many browser windows open at the same time, on pages I want to go back to and read later. Due to the way many pages are written, I usually end up with creeping memory usage until the phone is almost unusable.
However, after this upgrade, I noticed it seems much less aggressive at swapping out apps. When I expected it to be nearing 200MB, swap was only at 157MB. I noticed today a slight bit of lag when unlocking the phone (I do use the numeric lock), and I just looked (with 11 windows of various apps, including the browser) and I'm using 218MB of swap. I'm quite surprised as at this point it used to be painful switching between apps... it's not!

So, in short - if I had more time I'd be digging through your patches as I'm curious what kind of changes you made to make this dramatic an improvement.
I've been considering the N9 for a while ('cept it still costs too @(#& much for a device with no warranty in the US), but now I think I can hold off longer (the other problems can't be fixed by software changes, the screen is too small for my aging eyes and the poorly-designed proximity sensor is too sensitive for the heavy IR in S. Florida).

I haven't overclocked since KP47, I may just try it again with this kernel. :)

Thank you very much for making my N900 feel better than brand new!
