Interesting. Maybe you should ask Antonio for an updated version of the patch that he used to debug this issue. If you give me the output of it while
it's locked up, I might be able to figure out what's going on in your setup.

What is the easiest upstream tree for you to debug?

Sorry for the late reply but I was pretty "disconnected" in the last days.

Is the debugging patch still required? If so, I can dig in my buildroot and retrieve it.

I would appreciate it if you could post the patch.  I'd like to
see if I can get the bug fixed once and for all.....

Thanks,
Ben

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,
