I'm running the latest (Wednesday 3/19/08, I don't have the release # handy) svn build with madwifi drivers. I compiled for the ADM5120 target and booted up on a Mikrotik RB133. Everything works fine until I enable wifi. If I take out the "disable" line in /etc/config/wireless and reboot, I get the kernel Oops below. If I issue a 'Wifi up', the console (I'm using serial) just hangs. The fact that it hangs whether or not wifi is enabled in /etc/config/wireless makes me wonder if it's dying on harware scan. Hm.
