Folks,
I am having a problem on and off with my machine.
It is a NEC Ready 8951 (the output of dmesg is appended).
It seems that after prolonged periods of heavy use (8+ hours of interactive use) the machine will frequently lock-up. I'm pretty sure that this is a heat-related problem, but I'm not sure how to proceed from here to narrow it down.
When I take the panel off of the mini-tower, none of the internals seem hot to the touch. My CPU already has a fan on it that dumps the heat inside of the case. The power supply also has a fan to draw the cooler outside air in (I keep it about 74 degrees in my house).
I tried looking through the kernel messages that klogd puts in syslog, but when the machine locks up, nothing is logged. Rebooting is enough to start the system working again, although heavy use will cause it to lock up again.
Any thoughts?
