Found out the problem. PCI-E Max Payload setting in BIOS was set at 256. Setting this to 128 made everything work again. Guess these adapters don't support 256.

Noticed I couldn't ifup ib0, so started tracing this down. I've tried re-flashing and it doesn't help. I've also tried to find an "A0" rev firmware, to no avail. What am I missing?
