Hello all, Environment: I'm running 2.6.32 with a set of patches provided by Arch Linux: ftp://ftp.archlinux.org/other/kernel26/patch-2.6.32.1-1-ARCH.bz2. The patches appear mostly cosmetic, with some changes applied to ext4. Hardware: I have a D-Link DWA 652 which reports as an AR5008 in lspci -vnn. The card is functional in kernel 2.6.28. (I'm using it to post this email) The ath9k list indicated that the problem in rmmod may be in the mac80211b module. Here's the sequence of events: % sudo modprobe ath9k # no pertinent dmesg output % iwconfig # wlan0 not present lo no wireless extensions. eth0 no wireless extensions. % sudo rmmod ath9k # not sure why it's telling me "Killed" here Killed % dmesg | less ... ...
