Comment 49 for bug 193970

I confirm the bug (Thinkpad T61p with iwl4965 from linux-backports-modules-hardy) but not the workaround (only reset can bring wifi back on).

On software rfkill (Fn-F5 here) both bluetooth and wifi go off, but then wifi goes back on in 15–20 seconds. Pressing Fn-F5 again causes bluetooth to go on and wifi to go off, and after 15–20 seconds wifi is on again. Pressing Fn-F5 quickly a few times can cause wifi to go off forever (i.e. until reset).
