A couple of days ago I tried to update to -current via cvs and got
a kernel panic upon reboot. I tried again after a cvs update earlier
today with the same result, so it doesn't appear to be a transient
problem. I downloaded and tried the kernel from the Oct 15 snapshot
with the same result. BTW snapshot bsd.rd does boot Ok.

Below is a verbose boot of snapshot kernel followed by
ddb> trace
ddb> ps
ddb> ps /a
ddb> show registers
ddb> show uvmexp
ddb> boot reboot (working kernel from around Sep 10)
