Had a Pent 4 server running fc3 crash (kernel panic) and am rebuilding

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.
Were you able to see an oops message when it crashed? If not, then make
sure a X11 server isn't running, and turn on nmi_watchdog.
No. In the FreePbx default installation, CentOs and all of the asterisk
components are installed automatically. X11 is not installed, leaving
only a linux command line on the console. Since the screen has only 24
displayable lines, the interesting stuff scrolled off the top before the
kernel panic occurred.
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.
I'll give those a try. Gut feeling is oriented around FreePbx defaulting
to an smp kernel and this particular system is a single-processor
single-core Pent 4. I changed grub to load a non-smp kernel and still
waiting on recurrence (after about 24 hours).
