Description stephleg 2009-10-26 20:10:02 UTC
Hello,

I had a system freeze (mouse frozen on X, no keyboard) and a few seconds
later the system reboot. This is not the first time I have this problem,
it happens randomly may be once a week since around one or two months.
I don't know if it can be a hardware issue (?).  As I get a core this
time, here is the backtrace :

How-To-Repeat: The crash happens randomly.  Nonetheless, it seems that the crash happens
when the CPU and the disk are in an activity peak.
