Re: NETDEV WATCHDOG: eth0: transmit timed out

[Darryl Miles]

I am getting complete lockups of the NIC, up/down the interface doesn't
restore it.  rmmod/insmod of ne2k-pci and 8390 doesn't restore it.  A
reboot does.

The m/c with this card in isn't normally highly loaded on the network,
but under heavy load it will lockup completely (fairly reliably I
suspect).  I have also had this problem with 2.4.0-test11, I had traced
it to ei_tx_intr() in so much as it was calling the
"ei_local->stat.collisions += 16;" line.  This is 8390.c:635 in 2.4.0.

The log below shows the time I had reloaded the modules trying to bring
it back to life.
