Asus P5k, Intel Q9450, 8gb ram, x86_64, running 2.6.28. The on board eth0 atl1 never has a problem, only eth1 intel e1000, plugged into a pci slot. On a couple of machines, the way I got it to stop, was to use 8.0.6 intel e1000 driver with the patch below. (works on same hardware, running 2.6.27 kernels) I can't remember where I downloaded this patch from, but I haven't had an issue yet with it. [root@web6 SCRIPTS]# cat e1000-8-0-6-stepfix.patchquoted
