Has anybody noticed any problems with screenblank causing SS1's running
SUNOS 4.1 to panic.  This problem occurs (not every time) at boot up time
when screenblank is executed in rc.local, and has happened to several of
our SS1's and an SS1+.

The following messages are reported:

screenblank started BAD TRAP
pid 92, `screenblank': Data fault
kernel read fault at addr=0xf81a4fb4, pme=0x0
Sync Error Reg 80<INVALID>

Begin traceback .........
End traceback

panic: Data fault

When the machine is rebooted, all is ok. This problem did not occur when
running SUNOS 4.0.3.
