I saw some messages about this on the list, including a patch that
looked promising:
http://lists.infradead.org/pipermail/ath10k/2013-December/000888.html
but it didn't help.  I'm pretty sure stuck firmware is not something
you can warm reboot to fix.

On the other hand, when my box reboots itself, it always comes back
okay and the driver loads fine.  So clearly there is *some* reset line
in the system that's working...

Longer runs?  Lucky you! :)

Yeah, I tried the AP firmware and it lasts longer.  I'm pretty sad
that there are two different firmwares with two different sets of bugs
to choose between.
