I can reproduce this issue too and this happens only once - right after
association. After association, running a background scan doesn't show any
problems.

I have seen the wrong rssi in scan results but I just don't have yet
have a proof on clean
wireless testing. It seems that when I put a lot of printk I don't see
the problem because
maybe scanning/calibration/etc. is shifted more away. Anyway it's just a
guess so I will dig
further.
