Re: 3.4-rc2, ilwagn still most of the time completely unusable

[Norbert Preining <preining@xxxxxxxx>]

Hi everyone,

I am coming back to this old thread, not because it has been solved, 
but because today I got a funny new message while checking why 
everything got stuck again:
	[69588.972126] iwlwifi 0000:06:00.0: fail to flush all tx fifo queues
and after doing
	rfkill block wifi
	sleep 20
	rfkill unblock wifi
I got a kernel warning:

These messages now appear only now and then.
