FW: Kernel oops v2.4.31 in e1000 network card driver.

["Tim Warnock" <timoid@getonit.net.au>]

Further information to this:

Network card causing the problem is the intel quad port gigabit ethernet
pci card.
I have tested also on 2.4.27, 2.4.32 and the latest 2.6 series kernel.

Under load (10-15kpps) the network driver crashes. Under increased load
(20-30kpps) the driver will actually cause a full kernel panic and
reboot the box.

After replacing the card with a single port intel gigabit ethernet pci
card, the system has been rock stable.

According to intel, the quad port nic is based around the "Intel(r)
82546EB" controller, the single port nic is based around the "Intel(r)
82545" controller.

Are there any other known problems with Intel(r) 82546EB controller
support with the current e1000 driver?

I'm not on the list so can I please be CC'd?
