--- Comment #1 from Adrian Chadd <adrian at freebsd.org> ---
Hm, try compiling with AH_DEBUG / ATH_DEBUG / ATH_DIAGAPI, then do this:

sysctl dev.ath.0.hal.debug=0x4

then let me know what is printed when this happens.

So, the code '3' is HAL_EIO which in the reset path mostly indicates the
hardware isn't coming back from being powered off.

Also, compile the tools in tools/tools/ath and run 'athregs'; it'll give you a
register dump. Do it when it's working and when it's not working. It's possible
that the NIC has completely lost its mind and the register reads will return
error values - I'd like to know what those are.

Thanks!
