e1000 tx Unit hang on 2.6.28 and patch that works...

From: Doug Bazarnic
Date: Fri Jan 09 2009 - 16:47:50 EST


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.
