So, 
Now it has happened again. :-(

I can conclude that a rmmod/modprobe cycle does not help. 

Some logs:

At around noon, there was some hickup, from which we recovered:
Mar  8 12:54:30 tippex wlan0: deauthenticated (Reason: 7)
Mar  8 12:54:31 tippex wlan0: direct probe to AP 00:18:39:c0:5f:50 try 1

Mar  8 12:54:31 tippex wlan0: associated


The, at 15:18, we got the dreaded "No ProbeResp" again. Now I have a debugfs 
dump for that time as well:

The only way to get the interface back to operational status is to 
/sbin/reboot the machine.

Any ideas how this can be solved?
