RELENG_7 && ath && WPA && stuck when bgscan is active on interface

[Matthias Apitz]

Hello,

I'm running the above configuration, RELENG_7 kernel and WPA, on an Asus
laptop eeePC 900 for which one must patch the HAL with:
http://snapshots.madwifi.org/special/madwifi-ng-r2756+ar5007.tar.gz )
all is fine, mostly, but when 'bgscan' is activated on the interface
ath0 it get stuck reproduce-able after some time without any traffic through
the interface; setting 'ifconfig ath0 -bgscan' makes the problem going
away;

could it be related to the bug I'm facing on another laptop with
bgscan/WPA/iwi0, see:

thx
