I've run this with both the SMP-GENERIC (only modified to add the PS-2
mouse and DDB options), and my abbreviated SMP-GENERIC, which also
deletes all the SCSI, IDE, and network devices that I don't have on my
machine, which speeds up the boot time, and it fails in the same
place.
I only get the message
Enabled Ints 1,2,3,4,6,7,8,12,17,18, imeg: 0x00f9ee21
before it gets the fatal trap.
