Hello,

We have been capturing the firmware crash binary files from the AX200, I guess
it uses the same API as ath10k, so something just worked for once.

They are about 5MB each.  Is this something you can use to further debug
this?  I'll be happy to send them to whoever can make use of them.

It seems pretty easy to reproduce these transmit bugs, at least...maybe you
can just as easily reproduce it yourself?

Thanks,
Ben
