Panic in 2.8

Subject: Panic in 2.8

I'm mystified by the behavior of a 2.8 beta  machine I'm using for
test.  It boots and runs fine with a 2.8 snapshot boot floppy. The dmesg
is attached as dmesg.floppy.  If I boot from a 2.8 GENERIC built from
fresh source today, without power cycling the machine, I get a different
dmesg. It is attached as dmesg.ide.  The diff is attached as dmesg.diff.
If I turn the machine off for 30 seconds and boot off of the freshly
built GENERIC kernel, the machine panics.  This is completely reliable
behavior, if I turn the machine off, I have to boot the floppy and then
reboot without cycling power to be able to boot the freshly built
GENERIC kernel. A hand typed traceback is attached as traceback.
Clues?
