Their are two issues here. The original issue is a current bug, however the lockup is separate and fixed as noted below.
The other issues listed are SEPARATE and fixed in 2.6.27.11+ currently in intrepid-proposed.
The workaround is to sudo modprobe -r ath9k then sudo modprobe ath9k although there is a disconnect issue currently being worked through (several duplicate bugs).
