The dc driver in 1.2-Alpha (as of June 12) repeatably hangs a 5000/200
here, and has done since approximately June 5.  (or perhaps earlier,
June 5 was the first time in a while I'd rebooted that machine,
and it's been wedged from then until today)

The machine hangs immediately after printing
   adding dc0 subslot 0 offset 2000000

and sits there until the reset button is pressed.

I'd appreciate hearing a confirmation from anyone who's successfully
booted a 3100 or a 2100 with a kernel compiled from June 5 or newer
sources.

thanks
