Bummer. I thought you had finally found a way to blacklist the
NICs that cause all of the strange ath9k bugs :)

A good PCI and USB killer would reduce the debug load here as well! :) Thanks
for a good laugh.

These cards are meant for low-latency situations, primarily gaming.
I am still trying to find out if there are any HW quirks to be handled
in the driver, but they seem to just work with ath9k.
The 3x3 card is based on AR9380 and the 2x2 card is based on AR9462.
