As I read through this kernel bug and debug efforts, it occurs to me that the issue being debugged is a firmware crash, leaving the device in a high power state causing it to heat or perhaps heat causing firmware to crash first with the same result.

The patch in https://bugzilla.kernel.org/show_bug.cgi?id=61111#c22 is really a workaround that limits tx rates to avoid overheat at high rates, but is not going to be a solution for upstream for a number of reasons. It's intended for a workaround for the self built kernel (I can build this for you?) but expect
it's temporary in nature.

The last patch they have is trying to gather more information on why the firmware is crashing.. I'm curious if there is some problem in the firmware that should be monitoring the device temp and failing to take action on to avoid this issue they are trying to get a handle on. Saddly I don't have access to the firmware source to be able to do that.

I could also build a kernel for you that would include the firmware crash dump we could feed back to the kernel bug developer in hopes of helping them isolate the issue. I don't have your device to test with, are you willing to help debug the issue if you could get kernel builds?
