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 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 ;)

Cheers,

Auke
