Ben,

attached you have the patches we have been using during our debug.

They create a new debugfs file that you can read when the wifi is stuck
in order to gather some information about the queues/tids status. The
file is located in the ath9k debugfs folder and its name is "nodes".

I hope it can help.

Cheers,
