Hello Matt,

Hi Bernhard.  I talked to Michael about this and we'd like you to try
two things.

1) Can you disable iLo2 and see if you can still reproduce the problem?
2) Can you apply the following patch to get more information on when
   MMIO gets disabled?

Not sure this is going to help you. NIC crashed two times tonight, logs
look like this

at this point the "watchdog" kicked in and did rmmod/modprobe, so I
think the only thing you can read out of this debugging log is that
there was no kernel message right before MMIO got disabled and it takes
quite a while to fire the Tx timeout.

I'm now switching to eth1.
