Hi,
There seems to be a bug in the Linux 2.4.29 e1000 driver.
With an SMP kernel on a single Intel 3.0GHZ HT cpu, and an 82547 NIC in half-duplex 100Mb/s mode, the kernel with lock up hard (no nmi_watchdog=1 messages) under reasonably heavy transmit network loads. The bug does not manifest itself with a non SMP kernel, and does not appear to be there in full duplex mode on a fully switched network.
Using the e1000 driver from 2.4.28 or the latest 5.7.6 driver seems to fix the problem. I guess merging the latest driver would be a good idea.
The 5.7.6 driver is available from:
http://sourceforge.net/project/showfiles.php?group_id=42302&package_id=54835
I'm using an Abit p4c800-E Deluxe m/b, and have verified this is reproducible on similar machine with the same m/b.
Cheers,
===Rich
