I strongly support this. I recognize several of your problems from my
attempts at using ath9k with only a single STA which was all but stable.

This is also my impression. Since it is important for Atheros to have
bugzilla reports rather than discussion on list I will try to find
time for creating more and/or new bug reports about my problems.

(But the ones I have created so far did not really receive very good
response.)

Note that my AR9280 is not even detected correctly on PCI now so I
may switch back to AR5008 for that.

I really should try out FreeBSD too.
