:  Not really.  There could be another problem which should have been in your

Hey, all right! Except I'm running AOS, not AIX (I assume this is an
AIX-fix).  However, you did hit the nail on the head - I set the read and
write sizzes in /etc/fstab to be 1024 or 1280 or some nice even number like
that.  Suddenly things work (albeit somewhat more slowly) with the RS/6000.
I had experimented with raising the sizes and hadn't lowered them
sufficiently to discover this.

I'm using 4096 for inter-RT NFS (not sure if this is even valid, but it does
seem a bit faster than 2048).
