I have two IPC's that will every now and again go into an endless loop
displaying:

	Type b (boot), c (continue), or n (new command mode)

Stop-A doesn't help - only switching them off/on works (most of the time)

At bootup (using 1.3.3 Generic SCSI3) the problem sometimes occurs just after
the line:
cgthree at sbus...

1.4 seems to make things worse - the bcn line is almost guaranteed at bootup.

Have I miss configured something?
