Ugh.  I suggest you use the BIOS menus to increase the number of
interrupts which are allocated to PCI.  Make sure your NIC
and IDE are not sharing the same interrupt.  That way if
it happens again you won't crash and you won't screw your
filesystem.  But you'll need to reboot to get the interrupts
back.

If it becomes a problem the only known fix is to boot with
the `noapic' LILO option.  This will slow things down a little
because all interrupts go through the old 8259 to CPU0
only, but it doesn't seem to make a lot of difference.
