ahc crash in -current

["Steve Shockley" <steve.shockley@shockley.net>]

I tried compiling and booting from -current (downloaded tonight) and it
started crashing in ahc0.  I don't have the message handy (had to get the
machine back up) but it was "scsi bus reset" or similar.  I'd be happy
re-test it later if needed.  Dmesg from -stable below.
