I use an ath9k in an Asus eeePC 1101HA. Actually regardeless which stable Kernel I use, I get many disconnects from my AP and receive strength is very low (-106dB) or I get no scan results. The Problem was solved with Kernel 2.6.32-rc3 but I need to use an vanilla debian Kernel and put a compat-wireless packages among it. With this, regardeless if compat-wireless-2009-10-28 or compat-wireless-2.6.32-rc5.tar.bz2 I get this while booting: [ 6.287660] kernel BUG at /build/buildd-linux-2.6_2.6.30-8-i386-Tm0Lt9/linux-2.6-2.6.30/debian/build/source_i386_none/kernel/workqueue.c:192!
