[eepro100] locked up 4-port Intel NIC with RH 8.0 and eepro100 driver

Seems transmit no longer works out of the second interface...
Only the first two ports have a cable attached,
each to a tg3 GigE NIC with a cross-over cable. It ran for
about 3 days at 50Mbps bi-directional on two ports before locking
up. The machine was at 100% CPU utilization this entire time. After
stopping traffic for 1 minute, and then starting it again, it started
working again. The error I was seeing indicated trying to write to the socket
would block (EAGAIN). For what it's worth, I saw similar problems on
this machine with an rtl8139too when connected to a 10bt hub, but in
that case the rtldiag showed more problems, and lockups happened in
3-8 hours...
If this line means nothing, then it's possibly a user-space problem.
The Command register has an unprocessed command 0c00(?!).
