PMI: 0 0 0 28 Performance monitoring interrupts Rebooted and set up RAID to read from hard drive again. I reset the BIOS/CMOS by pulling the CMOS battery and holding the power button down 10 seconds. After booting up I got the same 100% CPU usage.

Since RAID config did not match due to the new hardware I restored it from disk. I reseated the memory card and the battery. Once I regained physical access to the box I completely swapped out the PERC controller with one from a parts server.

I also noticed that when I plug in a monitor at boot that on the CentOS loading screen the loading bars get to around half way then the screen blacks out (no login screen is shown). Does anyone have any suggestions as to how I may be able to find what is actually causing the CPU usage? I've looked through dmesg and didn't find anything abnormal.

The process that is causing the high load is events/1 (or events/3 the one time it happened on core 3). It is usually CPU 1 (2nd CPU) but out of about 10 boots it was CPU 3 (4th CPU) once. I replaced the card and reset the battery and got the server to boot again.Īfter booting up I noticed that one of the CPUs always goes to 100%. I recently had a crash on a Dell Poweredge 2850 that I traced back to a bad RAID memory card.
