Not even control P.  Only the RESET button works.

There is the problem.  Call Emulex and get the latest ROMs.

(I had this happen constantly under very high Unibus loads with a
local hack to 4.3BSD.  We moved the SC41/MS to its own Unibus and
the problems went away; we later got new ROMs, moved it back, and
the problem has not recurred.  I told Emulex about the bug long
ago; they did not seem to listen, but apparently newer versions of
VMS can work the Unibus hard enough to trigger it, and so they
found it.)
