Hello Dirk & co,

I did hit the very same errors ..."ieee80211 phy0:
rt2x00queue_flush_queue: Warning ...."

I installed fresh Ubuntu15.04 into my old Asus Eee PC901. (It has
different controller RT2790). At various earlier kernel and Ubuntu
versions there has not been any issues.

But now at new Ubuntu 15.04 installation - very annoying status  -
computer did authenticate ok, but after few seconds/minutes these half
dozen of these errors  with 0.5s interval and all wlan traffic stopped.
Only method to recover was to restart computer.  (I tried to start/stop
services - without success.. I'm not expert) And I updated kernel
version 3.19 => 4.0.0 => 4.0.1.. I did not notice any difference.

But finally I found solution. While reading various topics, then I
noticed that at my computer "network-manager" was not managing eth0
(cable connection) => I edited /etc/network/interface, just added
#eth0(at interface file there is only lo =loopback defined). =>and now
network-manager notices when cable connected/disconnected.

I cannot understand logic, how editing wired connection parameters did
solve wireless :-)  (and yes network cable is not connected :-)

So maybe issue is not related driver/kernel level? There is some network interface  odd/configuration topic?
When I changed the Network-manager setting, no more wlan traffic total stoppage. 
I can see some still warnings.. (e.g.  I can create error, when turning by wlan on/off). And most likely power saving could cause some too.

Best regards,
tarmo

ps. most likely the issue was created at bit special Ubuntu installation
process. PC901 has only 4GB disk, first I installed Ubuntu server
version only and then later manually installed Ubuntu desktop. At server
installation there was some "preferred network question". I could
imagine that left some "odd setup".
