meta-bug for suspend on gta02(kernel issue)

[GNUtoo]

hi, there are at least 3 suspend bugs on the om-gta02:

• interrupt issue
• alsa issue(I'm trying to fix it)
• get_capacity issue

[GNUtoo]

•  https://docs.openmoko.org/trac/ticket/2478 (alsa issue)
•  https://docs.openmoko.org/trac/ticket/2477

[GNUtoo]

There is also this bug:

•  https://docs.openmoko.org/trac/ticket/2479

[GNUtoo]

I don't think it will be possible to fix all theses bugs in time for the shr 2012.01 release....

So I propose switching back to 2.6.34, and continue working on it on a longer time perspective(maybe we could skip 2.6.39 and work on mainlining instead).

According to lindi on IRC it seems that 2.6.34 also suffers from :

• suspend bugs
• alsa bugs

Replying to GNUtoo:

According to lindi on IRC it seems that 2.6.34 also suffers from :

• suspend bugs
• alsa bugs

Denis.

But it seem that it's much better:
<lindi-> resume only fails about once every two months

I copied the kernel and modules of 2.6.34.8 from shr-testing2011.1 into shr-core-staging/027 image.
To make telephony work for me, I added leds-pwm to /etc/modutils/ and
changed symlink of alsa-default in /etc/freesmartphone/conf/openmoko_gta to alsa-2.6.34

Now I will test this for a few days and see how good it works as everyday-phone.

[elisa42]

In detail I did (besides copying kernel and modules)

# load leds-pwm which has been compiled as module in shr-testing2011.1
cd /etc/modutils/                           
touch leds-pwm                  
echo 'leds-pwm' > leds-pwm      
update-modules 
# use right scenarios
cd /etc/freesmartphone/conf/openmoko_gta/
rm alsa-default
ln -s alsa-2.6.34 alsa-default

I can't reproduce a suspend bug with a recent 2.6.39 gta02 kernel....

[elisa42]

from what image did you try the kernel?
i'd like to test it

[elisa42]

compiled 2.6.34 kernel with bitbake after localy merging gta02-2.6.34 head to master. it did fully build but kernel image and modules where there.
have this kernel running now with 6 days uptime.
