Hi,

I'm still struggling with this. I'm back to using ath9k driver. I have
several DWA-556 cards of which some works just fine, but some of them
are awful. I have enabled all possible debug features for ath9k driver
and I have noticed that there are a lot of GTT interrupts on those bad
boards. Can someone tell me what those interrupts are?

Also, with bad boards I get lot of following log messages:

kernel: ath: Reset ANI state opmode 3
kernel: ath: ANI parameters:
kernel: ath: ANI parameters:
kernel: ath: Reset ANI state opmode 3
kernel: ath: ANI parameters:
kernel: ath: ANI parameters:

What are those about?

regards,
Sami
