those changes. To do this you must have an up to date RELENG_7 code
base and then apply this patch:

Then rebuild your kernel. There should be no changes to user apps.
I tested this on a Thinkpad R51 / RELENG_7 / Atheros 5212 and I see no
problems with the patch. It builds and runs fine and doesn't seem to
do anything harmful. :)
I have a problem with this machine though (with or without your
patch): the wireless connection seems to be stalled every few
minutes. If I try to send some traffic over ath0 or make wpa_cli
reconnect it comes back for another few minutes.
The only cure for now seems to be "ifconfig ath0 -bgscan".
That sounds like it can be the same symptoms as I described on the
freebsd-mobile list earlier this week:
http://lists.freebsd.org/pipermail/freebsd-mobile/2009-February/011343.html
What clockrate do you run at? On my system (Thinkpad X40, Atheros
5212) the problem does not occur at kern.hz=1000, but it is present at
kern.hz=100.
Tomorrow evening I will investigate this further including testing if
"ifconfig ath0 -bgscan" makes a difference for me.
There are many many changes to the ath driver in head that are not in
stable. If I can get confidence in the hal backport I can try to bring
back some of those. But I need to do things in the proper order; I
can't backmerge a bunch of stuff, find something is broken, and then
have to bisect changes. So people need to help get the hal code in
place first.
