Comment 44 for bug 404626

Documented at <https://wiki.ubuntu.com/KarmicKoala/ReleaseNotes#Disabling%20Ralink%20rt2860%20wifi%20on%20EeePC%20with%20Fn+F2%20hotkey%20causes%20a%20kernel%20crash>:

Using the Fn+F2 hotkey to disable the wireless antenna on an EeePC that uses a Ralink rt2860 chip (EeePC 900 and 1000 series) results in a kernel panic that will hang the system. A fix for this issue is expected to be provided in a post-release update immediately after the Ubuntu 9.10 release. (404626)
