What is a Dell Poweredge 2450, in terms of chipset and processors?

To add another datapoint:
I just swapped the 350MHz PII in my Super Micro P6DGS (your generic
440GX dual slot-1 board) for a pair of PIII600Es. Since then, I have been
getting panics under both 4.0 and 5.0 current from trap 29 that seem
correlated to IDE disk I/O load.
The first crash dump I grabbed showed that the faulting address was
idle_loop + 64, which is at the cli instruction.
Trap 29 could come from processor fault 19 (SIMD), an APIC, or PIC. Since
cli isn't a SIMD instruction, I suspect the APICs or PICs but have yet to
instrument and test this hypothesis.

What do you get when you feed kgdb
frame 3
info line * (void *)frame->tf_eip
?
