hi,

There weren't any changes in net80211 between those times, and ath(4)
only has some changes for locationing; nothing that should cause that
particular issue.

I'll go update to the latest -head on something with that NIC and test
it out some more.

Try reverting sys/dev/ath/ and sys/contrib/dev/ath/ back to r302387
and test? (but leave the rest of the kernel as-is.)

Thanks,



-adrian
