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.
