iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2 on Intel Centrino Advanced-N 6205

[Luke Faraone]

Hello,

I suspect this might be the same issue as bug #1270808 , but that is marked "incomplete" and appears to be wrt a different card.

When I encounter this issue, I am unable to browse the web. The issue is generally not resolved until I toggle the RFKILL switch off and on, but returns later.

I did not commonly experience this problem on previous releases, but I recall seeing similar messages previously. This happens incredibly frequently for me; several times over a few hours.

It doesn't happen with all wifi hotspots; the APs in my university's wireless deployment seem to trigger this problem more than other environments.
