[solved] acer_wmi and wireless

i noticed that my wireless interface was no longer working. i took a look at /var/log/everything.log and this is what i found:

May  2 17:43:21 arch NetworkManager[2754]: <info> (wlan0): bringing up device.
May  2 17:43:21 arch NetworkManager[2754]: <info> WiFi hardware radio set enabled
May  2 17:43:21 arch kernel: [   56.932018] ADDRCONF(NETDEV_UP): wlan0: link is not ready

May  2 17:43:22 arch NetworkManager[2754]: <info> Policy set 'Auto eth0' (eth0) as default for IPv4 routing and DNS.
May  2 17:43:22 arch NetworkManager[2754]: <info> (wlan0): taking down device.

for some reason, wifi gets disabled by radio killswitch.

then i tried:

rmmod acer_wmi

and suddenly, the wireless interface was up and everything was fine.

is there any solution to this other than removing acer_wmi? presumably, the module is useful and it's worth keeping.

thanks.

Re: [solved] acer_wmi and wireless

updating to the new kernel (2.6.39) fixed the issue.
