Hmm... This sounds a little like a problem we're experiencing right now with
our Sequent Balance 8000. Occasionally the ethernet seems to get stuck in one
direction (ie, the Sequent can transmit packets, but everything to it ends up
in /dev/null). At first we thought it was the transeiver that was faulty, but
now we're not so sure anymore. (It got better when we replaced it with a newer
one (INMAC Clear Signal), but there are signs that it might reoccur again. Most
of the time things work just fine though (with Sun 3:s and SPARCs - no NFS
though, Dynix 2.1.1 doesn't support it...)
