I have not seen this.

Try 'ifconfig ath0 -bgscan'. Something causes my card to lose
association periodically when the background scan is in progress.

Are you running wpa_supplicant? Are you using WPA, WEP or running open?
I see the card get "stuck" when scanning. It scans channels, but only
for WPA secured APs. When needing to associate with a WEP or open AP, it
never leaves WPA mode, so never associates.
I am also running BETA2 on a 5212 card in a T43 ThinkPad.
