I've experimented a bit more. If I do an installworld and reboot,
the machine crashes in one of two ways (randomly):
#1 Crashes with a BTX error
int 5 err 0 efl 00010206 eip 00000012
eax 00000039 ebx 00023920 ecx 00023934 edx 00000000
esi 00000000 edi 0000000c ebp 000943c8 esp 000943cc
cs 002b ds 0033 es 0033 fs 0033 gs 0033 ss 0033
cs:eip 62 00 00 00 e8 05 04 00 00 90 31 c0 cd 30 58 01
ss:esp 1c 8a 01 00 00 00 00 00 6c 44 09 00 1a 00 00 00
#2 Loader has all sorts of 'can't find file BLAH' errors, stack undeflow
errors, and winds up at an 'ok ' prompt.
Trying to run commands from the prompt sometimes work, sometimes return
a 'stack underflow' error.

That's with the latest -stable /boot/loader.
If I take that machine and net-boot it, then mount / and copy a
/boot/loader from March 20th, then reboot the machine, the machine
now boots just fine.
If I put the -stable /boot/loader back into /boot, the machine dies.
If I put the March 20th /boot/loader in, the machine boots just fine.
Anybody have any ideas? What happened to /boot/loader between March
and now? I am at a loss.
