Subject: Re: [Regression] - 2.6.32-rc5 hangs using rfkill on an eeePC

Actually it was pretty easy to find the culprit, as thereare only two
eeepc-related commit between -rc4 and -rc5 and one is about the
camera.

Reverting:

[PATCH] eeepc-laptop: Prevent a panic when disabling RT2860 wireless
when associated

fixes the problem.

Commit-id is b56ab33d68638e6aafdbfc694025e8354a628f49

Regards,
Fabio
