ath (hostap) stuck beacon causes system to crash

[Erik Norgaard]

Hi:

I have a FBSD 6.2-STABLE box setup as access point with an ath based 
3Com NIC. At random, I get the following kernel error:

Jun 20 23:19:34 strange kernel: ath0: stuck beacon; resetting (bmiss 
count 4)
Jun 20 23:19:34 strange kernel: ath0: ath_reset: unable to reset 
hardware; hal status 3
Jun 20 23:21:57 strange kernel: ath0: device timeout
Jun 20 23:21:58 strange kernel: ath0: stuck beacon; resetting (bmiss 
count 4)
Jun 20 23:21:58 strange kernel: ath0: ath_reset: unable to reset 
hardware; hal status 3
Jun 20 23:22:12 strange kernel: ath0: device timeout
Jun 20 23:22:13 strange kernel: ath0: stuck beacon; resetting (bmiss 
count 4)
Jun 20 23:22:13 strange kernel: ath0: ath_reset: unable to reset 
hardware; hal status 3
Jun 20 23:22:27 strange kernel: ath0: device timeout
Jun 20 23:22:28 strange kernel: ath0: stuck beacon; resetting (bmiss 
count 4)
Jun 20 23:22:28 strange kernel: ath0: ath_reset: unable to reset 
hardware; hal status 3

After which either the ath interface stop functioning, I can login and 
reboot, or the system crashes and reboots, or the system just locks up 
completely and I need to reset it.

I have this line in rc.conf:

ifconfig_ath0="inet 10.0.0.1/24 ssid MyWifi mode 11g channel 6 mediaopt 
hostap"

The error occurs at about any time, including 5 in the morning when 
there is no wireless traffic.

I see no mention of this problem in the bug reports, but did find a post 
from 2005. However the suggested solution seems more like a workaround. 
Any clues how to solve this?

Can neighbouring networks using the same or adjacent channels cause this?

Thanks, Erik
