Ok,
The kernel was built from CURRENT source checked out at about 17:00 HST on
Aug 29 (03:00 Aug 30 GMT). The mirror I use can be as much as three hours
delayed from what I see on the commit messages.
I attempted to set the debug link2 as suggested and the link became too
lossy for our code which then removes all routing through the ath card. I
also get lots of "ath0: hardware error; resetting" errors with the
debugging set.
ifconfig from our ath0:
ath0: flags=8a43<UP,BROADCAST,RUNNING,ALLMULTI,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.5 netmask 0xffffffff broadcast 10.0.0.5

status: associated
ssid phop 1:phop
channel 2 authmode OPEN powersavemode OFF powersavesleep 100
wepmode OFF weptxkey 1
All other cards in this case are wi.
A snippet of the output from debug link2:
(the hardware errors happen about 3-4 more frequently with this set)

I don't have a kernel config available, but it's basically GENERIC with the
following additions:
options HZ=250
options CLK_USE_I8254_CALIBRATION
options CONSPEED=19200
options IPFIREWALL
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPDIVERT
options MROUTING
options NO_SWAPPING
