2.6.11 e1000 EEH MMIO failure

[Sonny Rao]

I'm guessing this means a bad e1000 card but I wanted to check with
the experts.  The box is a p690 w/ some expansion drawers attached, 
and is running a pretty-much stock 2.6.11 kernel, system is booted in
SMP mode. 

Could it be related to e1000 errata "23" mentioned earlier on the
mailing list?

Here are the messages:
