Well, maybe they are well-known in OpeWRT community :) I believe we
didn't have any reporters here. Unfortunately OpenWRT guys don't
report their problems, fixes too often.

Ouch, I didn't know DMA errors also happen for BCM4322. My 14e4:432b
one was working fine. Maybe this is Mini PCI vs. Mini PCIe? Do you
know if your cards are PCI or PCIe?
