I have had the same experience with 80MHz CPUs in my SS20. I finally
had
to settle for 2x50MHz and some stability instead.

Hmm- anyone managed to get the SM81s to work reliably in a SPARCstation
20 SMP?
I have a SS20/2xSM81 as my SMP Sun- haven't used it much yet but if in
general they have stability issues I should probably do something else.
I ran a SS20 with Dual ROSS 125MHz CPUs. They got seriously hot. Also ran
another SS20 w/Dual SR71s. Both the SR71 and ROSS needed an unique EPROM
upgrade to run without "freezing" (hanging) the system. Perhaps that's the
issue with your SM91-2 (as opposed to heat)???
You might want to post a query to the suns-at-home at
net-kitchen.com list to get
the EPROM upgrade if required for the SM91 (if someone else doesn't respond
on this list with same).
Cheers,
Lyle
