Will test older kernel soon. Can provide details/logs if you want 'em.we've already established that Allen's issue is not due to the driver and caused by interrupts being mal-assigned on his system, possibly a pci subsystem bug. You also have a completely different board (82572EI instead of 82571EB), so I'd like to see the usual debugging info as well as hearing from you whether 2.6.19.any works correctly.
On 2.6.19 the link status is working (follows cable plug/unplug), but no tx or rx packets get thru. Attempts to transmit occasionally result in tx timed out errors in dmesg, but I cannot seem to generate these at will.
On 2.6.20-rc5, the link status does not work (link is always down), and as expected no tx or rx. No tx timed out errors this time, presumably because it thinks the link is down. Note that both the switch and the LEDs on the NIC indicate a good 1000 Mbps link.
dmesg, 'cat /proc/interrupts', and 'lspci -vvv' attached for 2.6.20-rc5. The data from 2.6.19 is essentially the same.
On top of that I posted a patch to rc5-mm yesterday that fixes a few significant bugs in the rc5-mm driver, so please apply that patch too before trying, so we're not wasting our time finding old bugs ;)
I haven't been able to test rc5-mm yet because it won't boot on this box. Applying git-e1000 directly to -rc4 or -rc5 results in a number of rejects that I'm not sure how to fix. Some are obvious, but the others I'm unsure of.
