I have now disabled the debug option again. And rebuild some new kernels
(3.2.0-rc1 and top git).

And what I stil see is that the tx-queue gets stuck and does not
recover without rmmod iwlwif.

hwq 11: read=0 write=0 stop=1 swq_id=0x2e (ac 2/hwq 11)

But I still am using the patch that you sent to disable power save,
so it is not only this one.

If you think I shouuld turn on power debug again and see hope that
it happens again, let me know.

Furthermore, I have now seen hiccups on my home router, too, at
times. There is recovers normally by itself, but still.

Best wishes

Norbert
