Does the box use interrupt sharing? There are also a lot of people on
linux-poweredge@xxxxxxxx that see interrupt only handled by the first
processor.

I could get this on a pe2550 that shared interrupts with a gigabit nic. If
you loaded NFS enough it would lock up.
These dell boxen are quite sensitive to the issue. Perhaps because of the
serverworks chipsets.

Did you do the interrupt trick?
Switch of what you don't need in the bios and reboot.
Go into the bios and switch on the scroll,caps and num lock.
Press Ctrl-E and system should beep at you.
reboot.
It will nog have reassigned the IRQ table.
