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 - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
