> Only exception I ran into is wireless card in an old MacBook Pro which should work but doesn't.
If this was a bwi(4) card, the problem is probably fixed in 5.6: http://marc.info/?l=openbsd-cvs&m=140585757928895&w=2

I've seen others get the same error, funny enough the man page says: athn0: device timeout A frame dispatched to the hardware for transmission did not complete in time. The driver will reset the hardware. This should not happen.
The device timeout message might not necessarily be a fatal problem. If it doesn't have an impact on actual usage you can just ignore it. Otherwise, please file a quality bug report so we can learn more about it.
