Hi,

I'm hitting subj issue, at some random point mentioned card stops
packet processing and stalls,
and I'm getting a lot of "iwlwifi 0000:03:00.0: fail to flush all tx
fifo queues" lines in dmesg.

wpa_supplicant does not even notice that it's disconnected, and does
not try to re-establish wireless connection.

Looks like many users suffer from this issue, please see:
https://bugzilla.kernel.org/show_bug.cgi?id=48921

Looks like there's no fix except disabling 802.11n functionality. It's
not an option, nowadays internet connection is faster than
802.11g speeds.

Can we get any public comment from Intel devs?

Regards
Vasily
