My desktop machine started having random crashes last summer when
I installed Fedora 13 (x86_64) on it. Now I upgraded to Fedora
14, and this has only got worse: before, uptimes could be
anything between 3 minutes and a month, now it's a few hours
at most.
I never found anything interesting in the logs.
When running without X, during a crash I saw a message on the
console mentioning mcelog, so I installed and used it as a
daemon, and also via
/sys/devices/system/machinecheck/machinecheck0/trigger as
described here:
http://www.kernel.org/pub/linux/utils/cpu/mce/README
But it didn't report anything.
I checked temperatures with sensors: nothing. Ran memtest86+ for
hours: the same.
Is there something else that I should check?
