Sometimes after a cold boot the cpu fan doesn't start and /proc/acpi/thermal_zone/temperature increases to 95 and the system shuts down.
This happens on FC1 and FC2, on RH9 the fan starts after a couple of minutes.
I recall something like "echo 1 >/proc/acpi/thermal_zone/something" and I don't mind to do that in rc.local if I only knew that something.
P.S. It's a Compac Aramada 1750
