Network in 2.0.35 stops working(DEC DC21142) again

[Dominik Weis]

The network on a server with kernel 2.0.35 stoped working again. That is
the third time that this happend in the last month. The first two craches
happend with de4x5.c network driver and I did not get any error log. I
changed the network driver to tulip.c(tulip.c:v0.89H 5/23/98) and this
time I got an error message after 8 days uptime. The sytem is a Dual PII
with 400 Mhz running 2.0.35. The load was not very high when it happend
only three students were using it at the time.

I got this message over and over till I restarted the network:
