Re: [Regression] Problem with rfkill on 2.6.38

Hiya,


No worries about the late reply... was running around for the last
couple weeks at various events so haven't had a chance to test any other
suggestions yet anyway.

'Twas brillig, and Johannes Berg at 09/05/11 09:36 did gyre and gimble:

Looking at the only commit available for this module on this cycle I see:

http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=commit;h=a3d77411e8b2ad661958c1fbee65beb476ec6d70

dell-laptop: Toggle the unsupported hardware killswitch

It is found on Dell Inspiron 1018 that the firmware reports that the
hardware killswitch is not supported. This makes the rfkill key not
functional.

This patch forces the driver to toggle the firmware rfkill status in the
case that the hardware killswitch is indicated as unsupported by the
firmware.





This looks pretty suspicious to me (from the description) and sounds
like this could be an unintended consequence of the changes here.

I'll see if reverting this one fixes the issue. Thanks for the insights!

Col
