After a bit more testing....  loading either ide-scsi or
ide-cd is sufficient to lock my system dead dead dead if
the bios is set to Enhanced mode.

After _not_ loading ide-scsi or ide-cd I was able to boot in
Enhanced mode.  I think I am getting some sortof wierd interrupt
storm.  Everything freezes for a few second every so often...
Here is what I am seeing.

I have a P4 with hyperthreading so my kernel is SMP.  The huge
number of interrupts on 18 (I'm not doing very much beyong ssh to
another box to write this email) looks suspicious to me.

yes.

I'll check...
