2.6.11 e1000 EEH MMIO failure

[Linas Vepstas]

Recent e1000 code has some new kind of whiz-bang watchdog timer
code that is causing the device to DMA off into hyperspace,
thus triggering the EEH code.  It's not clear to me if the
2.6.11 kernel has this code.

Am cc'ing two people who should know....
