Subject: e1000 tx Unit hang on 2.6.28 and patch that works...
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 cant remember where I downloaded this patch from, but I havent had an
issue yet with it.
