Sounds like the bug with the scheduled work locking. See the
"mac80211/bcm43xx deadlock" thread, there's a patch, report back if you
can/can not reproduce with the patch.
Hello, sorry for the delay but I only managed to try it out today..
I've applied the patch and tortured the system as far as I could, and
no hang at all :)
I've read the thread and it apparently replaces one bad problem for a
lesser one, so I understand if it's not applied.. But at least there
is a place in the code to point as the culprit :)
Thanks,
Renato Caldas
