Had a Pent 4 server running fc3 crash (kernel panic) and am rebuilding from scratch. I installed FreePBX (CentOs) from scratch and asterisk was running, but had not yet been configured. It too crashed with a kernel panic. Ran memtest for 24 hours; no errors or issues uncovered. I then noticed that FreePBX installed using a SMP kernel (and grub indicated a non-SMP kernel was installed as well). Would running an SMP kernel on a Pent 4 potentially cause a kernel panic? (Or, do I need to dig somewhere else?) Nothing in the logs to suggest a root cause and I'm now waiting on recurrence using the non-SMP kernel. R.
Well, are you running an SMP box, or is it just hyperthreaded? I know there are issues with running an SMP kernel on a machine that's only HT.

If not, then make sure a X11 server isn't running, and turn on nmi_watchdog. The easiest way to capture the oops is with a serial console, but hand typing the text into another computer or a snapshot has worked in the past also. Then post your results. Also check the system temp with lm_sensors and the quality of your drives with smartctl. Mike
