I have the same hardware as you, and this problem has been there for a
long time. AFAIK this only happens with dynamic executables and, as you
say, seems to be random (from a user's perspective at least).

Others can correct me here, but IIRC the problem is in the cache
management code. I thought this had been fixed already, at least
for the R4000 series, R5000 is a bit different and R8000 is a completely
different beast. 

I can't comment on the rest because I've always netbooted with a serial
console, but maybe Rafal or ther other SGI-clued NetBSDers can fill in.
I've been wanting to try a more recent 2.0 snapshot for a while, and it
would be interesting to hear some success stories on the matter,
specially on Indy hardware.

Btw, I always used your phx assembler for my Amiga coding back in the
day, great piece of software :)

Cheers,
