--- Comment #2 from Timothy Pearson <tpearson@raptorengineering.com> ---
I can confirm the igb driver is also affected.  It appears that as soon as =
CARP
transitions from BACKUP to ACTIVE something happens that causes invalid DMA
to/from the card.  X520 cards are confirmed not affected, using the ixgbe
driver.
