[comp.unix.ultrix] TU81+'s on an 8700

I was wondering if there were any other sites on the net besides us
that have TU81+'s on an 8700.  How are they?  Do you have any problems
with them?  We have 2 of them, and we are having some problems with
them.  Some of the symptoms are:

1) Tape drives becoming unavailable to the system.  Problem goes away
when we reboot.

2) Segmentation faults when opening /dev/rmt0h,

3) hanging in the tape driver (tmscp).

We have received two patches from DEC.  The first one got rid of
problem 1).  Unfortunately it seems to have caused problem 2).  The
updated patch solved 2) but caused 3).  So we reverted to the original
DEC binary (it was better to lose the tape drives and reboot late at
night than to have it crash or hang during the day...).

Last night it looked like problem 2) had come back.  (We just
installed the patch to fix the dev major/minor -> 0,0 problem.)
