[SOLVED] Complete system crash / Debian Testing AMD64 / Thinkpad T520i

Buumi · 04-24-2013, 09:37 AM

I installed Debian as second system to my laptop and I'm having a problem there. I'm facing complete system crash occasionally, so far always when I've left my computer alone for a while. My system is Debian Testing 64bit and I'm using official repositories. My sources list:

Code:

# 

# deb cdrom:[Debian GNU/Linux wheezy-DI-rc1 _Wheezy_ - Official Snapshot amd64 NETINST Binary-1 20130214-22:44]/ wheezy main

#deb cdrom:[Debian GNU/Linux wheezy-DI-rc1 _Wheezy_ - Official Snapshot amd64 NETINST Binary-1 20130214-22:44]/ wheezy main

deb http://ftp.fi.debian.org/debian/ wheezy main non-free contrib
deb-src http://ftp.fi.debian.org/debian/ wheezy main non-free contrib

deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

deb http://cdn.debian.net/debian experimental main

Only think, I've installed from experimental is apt-get install -t experimental iceweasel and system crashed even before that.

I think on first time I didn't get any error log but last time I found this from my kern.log:

http://paste.debian.net/55

My system is: Lenovo Thinkpad T520i
Intel Core I3-2350m
Intel HD3000
4GB RAM

What do you think? Is my install corrupted or is that some known issue I'm facing?

Edit: To add some more info. I'm using XFCE and I've tried to launch it from lightdm and slim. I haven't yet experienced crashes when I'm at computer but that's not probably because that couldn't happen but because I can leave computer on for longish time. The crashes occur pretty often, once or twice a day.

It's a kernel bug: http://lists.debian.org/debian-kerne.../msg00007.html

Try the 3.8 kernel from experimental and see if that fixes it. Though any bug fix should come to the (soon to be) stable kernel as well.

I'll test that, let's see if it works. Hopefully fix comes to official kernel too, using stuff from experimental feels dangerous.
I'll report if it works, I guess I'll see that pretty fastly as it used to crash daily.

Thanks!

Edit: I now installed Wheezy again but I'm still facing the problem. I now try with the 3.8 kernel to see if it still happens and to be sure it's kernel's bug. I haven't had those crashes on Slackware 14 at least but I'm running 3.8.7 kernel there.

Edit2: I've been running 3.8.5 and no crashes so far.

Yet another edit: Now I've run 3.8.5 for a few days without a single crash so it probably indeed was an kernel problem. Let's hope it gets resolved on stable kernel soon but I'll mark this thread as solved.
