Something is wrong with scanning -- this (and a similar) sysassert popped up in multiple reports. For some reason, some channels get marked "active allowed" which upsets the firmware for good reason, this shouldn't be happening. Must be something in cfg80211? I can't see from the code how ... Can you paste output of "iw list" after loading the module and after the sysassert?

Pierre, can you please send the output of debug=0x800. Unfortunately, I can't reproduce it on my setup.
I attached a debug dump to bug 917034. Is that one sufficient?
This seems like a strange problem, channel 149 is disabled but still scanned? Can you try this patch please: http://p.sipsolutions.net/41b2db3eaebe260a.txt
I have an idea about how this can happen, to verify can you please attach the output of "iw wlan0 scan dump -u" just after this happens?
Bah. For some reason I haven't been getting the SYSASSERT anymore (connectivity loss still there though). Hopefully I'll get the full breakage soon...
Got it. These dumps are with the following SYSASSERT: [ 990.856205] iwlwifi 0000:03:00.0: Microcode SW error detected. Restarting 0x2000000.

can you please send the full dmesg? I am interested to know what happened before. Thanks
Created attachment 705806 [details] iw wlan0 scan dump -u (connectivity loss) This is the first dump, when connectivity was lost.
Created attachment 705807 [details] iw wlan0 scan dump -u (if down, SYSASSERT) Second dump, after ifdown wlan0. This is when the SYSASSERT appears in dmesg.
Created attachment 705808 [details] iw wlan0 scan dump -u (if up again) Last dump, when the module has been reloaded and the if is up and associated again.
Created attachment 705809 [details] dmesg
ouch - you didn't have the SCAN debug enabled :-(
