Hello, i am running Opensuse 12.2
I have had a couple system freezes where i can't ctrl alt f2, or ctrl alt delete or do anything. Sometimes i've had clementine playing music and it plays one second of part of the song over and over.
I have to hold the power off button and reboot.
Although it does this rarely, it really bugs me when computers do this and i'd like to find out what is causing it so i can help remove this issue.
<alt><sysreq>k will only restart the graphical environment; this used to be <ctrl><alt><backspace> and that might still work on your system.
Note that <sysreq> often shares its key with another functionality like <printscreen>; you need to use <ctrl> in that case; so the combination becomes <alt><ctrl><sysreq>reisub
And on laptops, it might involve the <Fn> key.
If nothing, boot up memtest86 to check the RAM sticks.

Thanks, I checked this not to long ago, there were no errors.

It is not an old computer. It is a:
Lenovo Thinkpad X220
6GB ram, 2 dim. (2gb) and (4gb)
Intel® Core™ i7-2620M (2.7GHz, 4MB L3 cache)
Intel HD Graphics 3000
Modified 9.5mm, intel 320 series 600gb SSD (modified to fit 7mm hard drive bay)

Thanks for that, i wasn't aware of that key combo.
Hey guys i'm still having this issue. Recently i installed Slackware 14, and i'm encountering the exact same freeze problems in Slackware, too, so i'm starting to suspect it's a hardware problem.
It's just occured while i was running Slack, even that reisub key combo is paralyzed, and i know i'm doing it right because i practiced using it so i knew exactly what to do.
Luckyly, Slackware does have a '/etc/syslog', but it doesn't have a kern.log file.
Here are all my /var/log files from Slackware.

Have checked to see if you're overheating? I ask because my machine was freezing up, before by dc adapter went out. So when I replaced it I found that the vent for the fan was clogged. Cleaned it & haven't had a problem since.
If you haven't already install lm-sensors.
run command
Thanks for the suggestion EDDY1, i've just installed that package on my Debian partition. My cores are running at 52 degrees C at the moment apparently. 86 is regarded as high.
I just thought of something the other day that i thought may be causing this. I have experienced these freezes on Opensuse 12.2, Debian 7, and Slackware 14. I never got these freezes on previous versions. I was thinking it may be due changes in the kerenl.
Opensuse = linux-3.4.6
Debian = linux-3.2
Slackware = linux-3.2.29
My computer is a Thinkpad x220 with Intel HD Graphics 3000.
To enhance battery life unde Gnu/Linux i'd always been running the following kernel parameters.
To be honest, i don't know what they actually do, but i know they give me around two and half more hours of battery life on my hardware. Because of changes in the kernel, i was thinking that these parameters may be affecting my system in a way that they never used to. I have temporarily removed these parameters to see if the freezes continue. So far i've been running Debian for four days with no freezes, but i wouldn't say the freezes happen that often either, so i'm still testing. I just wanted to share this theory to you guys who know what your doing, to get an idea if these parameters may be the reason my systems freeze?
