I got a panic from -current (02/05 approx 4am EST)
It looks like a problem with the pcm driver. I've removed pcm from my
config, and my machine boots ok now.
I can also boot fine with pcm in my config from a kernel and world
from jan 18th.
Here's my config (when it panics):
config file with xl0 and pcm
Here's a dmesg from my the same kernel (with pcm, that panics):
dmesg.boot
Here's a dmesg from the currently booting kernel (without pcm):
dmesg
Here's the panic:

Can anyone shed some light on this?
