Yeah, that commit is near some changes that might cause what you
are seeing though, so maybe you made a wrong turn along the way?
E.g. "ath5k: Update reset code" introduced a bug for RF 5413 chips,
maybe others.  Another possible change is the txpower rework.

BTW, can you (re?)post the "Atheros AR5212 chip found (MAC xxx,
PHY xxxx)?"

Also at least /net (you can add multiple paths to git bisect).  If 
you can narrow it down to a small range then a bisect over the entire
tree would eliminate any doubt, but in that case it's easier to make a
bisect mistake.  As you say, it does sound like a driver issue though.

Yeah, unfortunately I don't really have any good ideas, but I've seen
a trickle of similar reports so it would be good to nail it down.  Thanks
for testing, it really helps a lot.
