It lost interrupts. I had a testcase that should have received three
interrupts and only two were received by the driver. 100%
reproducable. Card used MSI-Interrupts (no MSI-X) and worked
reasonably well otherwise. But it is a prototype, so the card is just
as likely to be the cause as the motherboard.

Possible, yes. But I wouldn't know how to prove it.
Asrock G31M-S with Intel E5200.
