Hi Arend,
I noticed in some log you sent that your regulatory domain is set to
GB, which makes sense. I submitted a patch [1] last week so could you
try that and let me know the results.

Thanks for the update. Yes, my AP is on channel 13 so might be affected
by this.
That line is in brcms_c_wait_for_tx_completion()
main.c,8006 WARN_ON_ONCE(timeout == 0);
Would using another channel be any different for this?
I actually did not expect that warning to come up with the patch in place.
So if you can try another channel in 1-11 range and let me know the result,
I might be able to make some sense of it all.
Sorry, I misremembered.
It was already on channel 11, but it had 20/40 MHz bandwidth selected with
channel 9 as the extension channel. That might have been OK on channel 13,
but I think these two overlap.
Also I'm not sure if this is a standard mode, so I've turned it to just
802.11n+g mode, with 20MHz BW on channel 7 now. Output from "iw dev wlan0
scan" for reference.
Attempting to connect with NM no longer gives the kernel warning, but stull
no luck.
