I have a similar problem on -current - I boot from a SCSI disk, known
usually as sd0; if an external firewire disk is conected during boot,
*sometimes* (I haven't been able to find out exactly when, but it
happens occasionally) it gets recognized by the kernel as sd0, leaving
the system disk as sd1; the boot obviously fails at this stage; I have
to turn off/disconnect the external device in such ocasions.

No bother, though. I might recomile the kernel with the above fix
sometimes to try it.
