CPU #1 not responding - cannot use it.

I think this will be useful to others because I have a server that kept crashing mysteriously during intense disk usage/RAID checks. It would only crash during the weekly RAID integrity check.

ThenI noticed during a reboot that not all CPUs were being brought up, as a result this actually creates much higher temperatures with the output I got from sensors, just booting the system produced higher than normal temperatures.

You can imagine that a full blown RAID check would create a lot more strain, and probably resulted in the crashes I've been seeing. I've since upgraded the kernel and rebooted and did 3 manual RAID checks and the system has not crashed.

The real question comes down to this, was this a hardware issue or a kernel issue? I guess time will tell.
