There has been a bug in the 2.4.x series of kernels for a long time (at
least -pre9) concerning SMP and ne2k-pci.
Maciej W. Rozycki posted a patch back during 2.4.0 that fixed this problem
"[patch] 2.4.0, 2.4.0-ac12: APIC lock-ups" in late January. I've been
trying new kernels regularly since, and the patch doesn't seem to have
made it in (tested 2.4.2, .3, .4 and .5). Falling back on my patched
2.4.0 works fine.
Symptoms: Network driver locks up. Repeated messages of "ETH0: Transmit
timeout" occurs. Unloading and reloading network drivers does not help,
reboot is required. Usually only triggered by heavy network traffic
(300-400 megs at 700k or so usually does it).

This fits exactly my problems I mentioned a couple weeks ago. Same
question here. Therefore my question: can we expect to see this patch
implemented? If not, any other suggestions?

Quoting rc@zarq.dhs.org from ml.linux.kernel:
:There has been a bug in the 2.4.x series of kernels for a long time (at
:least -pre9) concerning SMP and ne2k-pci.
:
:Symptoms: Network driver locks up. Repeated messages of "ETH0: Transmit
:timeout" occurs. Unloading and reloading network drivers does not help,
:reboot is required. Usually only triggered by heavy network traffic

I concur. This happened to me tonight with:
Linux nice 2.4.4-ac9 #1 SMP Wed May 16 16:17:59 MEST 2001 i686 unknown
Here's the syslogs, flushed to the remote loghost machine somehow,
before the network became dead (closed connections, at the end of the
logs).
NB: It all started with an APIC error (unexpected IRQ trap, meaning
an error that passed through checksum controls).
