I have seen this too, on the same hardware. A HP DL145G2 with 4G
memory; after touching the SATA disk (immediately after selecting a
shell going into single user mode, after the date/time display on a
multiuser boot) the system panics.
This is using PseudoRAID, not gmirror.
It worked with 6.0-BETA1. I think it broke with BETA5, but it could
have been shortly after.
Also, after failure, the ar(4) mirror is broken. "atacontrol rebuild"
stays on 0% with BETA1. The rebuild works if I run it after booting
from a 5.4 CD.
