Jan gave me the card. I've set it to a rather busy channel (2.4GHz channel 
11), created a monitor interface, attached tcpdump and then waited what 
happens. I didn't get anything and then I've tried to set runtime-pm and deep-
sleep to 0. This didn't change the behavior for me at lot. I saw two packets 
and then it went silent again.

I wanted to try the same on a different card (ath11k) in the same system. But
it crashed my complete system - so I had to recreate the test setup. This time, 
I've set runtime-pm + deep-sleep to 0 before creating mon0. After doing this, 
it seemed to work.

Kind regards,
	Sven
