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:
# 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:
My system is: Lenovo Thinkpad T520i
Intel Core I3-2350m
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.
