Hi Maciej,

The important information is not what you posted here, but still in the
dmesg file you provided. In that log we see the following right before
the warnings:
[ 163.126590] wlan0: direct probe to AP 00:1b:11:f6:0f:28 (try 1)
[ 163.130027] wlan0 direct probe responded
[ 163.130032] wlan0: authenticate with AP 00:1b:11:f6:0f:28 (try 1)
[ 163.131924] wlan0: authenticated
[ 163.131952] wlan0: associate with AP 00:1b:11:f6:0f:28 (try 1)
[ 163.134325] wlan0: RX ReassocResp from 00:1b:11:f6:0f:28 (capab=0x431 status=0 aid=1)
[ 163.134331] wlan0: associated
[ 163.155938] wlan0: deauthenticating by local choice (reason=3)
It shows that association was successful, but something in userspace requested a disconnect.

I cannot get an exact line match based on the kernel information you
provided. I assume it is the first warning in
ieee80211_scan_completed(). This is not serious as it indicates that
mac80211 received a "scan completed" indication when it was not
scanning.

This warning has just been reported in linux-wireless also. Perhaps you
can follow its discussion there. See
