Re: Randomness that no one can do much about

CADR2 got "wedged" this evening.  There was no visible response to boot
in the pc lights (0.0000).  It didn't respond to the debugging cable;
probably the Unibus arbitrator was hung.  When I did (dbg-reset) so
that I could look at the state of the machine, that fixed it completely.
The wedgage occured while a user was using in more or less ordinary fashion.
