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. Regards, Jan Mikkelsen
