My system randomly crashes. I cannot reproduce the crash except using this command:

echo c | sudo tee /proc/sysrq-trigger

Everytime it crashes (like once a week). I can boot and work with the machine, but at some point it crashes. I did the normal kernel updates and installed and uninstalled several things. This did not affect the problem.

Ich am using 13.04 64bit. Here is the link to the syslog of the time of the crash

So, any suggestions? I do not even know if it is a software or hardware problem...

If you have time for it, run a memory test. Often random crashes are caused by broken memory. I'm not an expert regarding the Kernel, but it seems to me your crash occured during memory allocation, what might hint towards this. Memtest86 should be included on most Linux installation CD's. –  soulsource Jun 24 '13 at 11:43
