First thing is that there is a iwlwifi driver or ucode problem as it asserts every time (it seems) when mac_config is called for channels 38, 42, 46, and 52. Channel 36 succeeds. The cause of the ucode error is unclear to me as I am waiting for somebody to get back to me about what the contents of that "event log dump" means. I looked further about why mac_config is called for those channels and the reason appears to be that it is done from ieee80211_sta_scan_work. This should not happen as it should only do so for sw scanning (if I understand correctly), while the default for this driver is hw scanning (and the user is not overriding the default). I am thus now trying to figure out how it actually thinks sw scanning is enabled through some simple debugging where mac80211 tries to run the driver's hw_scan function. Explicitly enabling sw scanning is an interesting idea. Marcus: could you please run your test twice with that patch? The first time you run it as you did before, the second time please provide the driver parameter "disable_hw_scan=1" together with the debug parameter.
