Hi,
since v3.19-rc1 I have problems with WiFi (Intel Corporation Dual Band
Wireless-AC 7260) on my laptop. Trying to disable all the radio devices
(WiFi and BT) with the function key of my laptop, which should hard
block the rfkills, causes the following message to be repeated over and
over until I re-enable them again with the function key:
[ 593.746001] iwlwifi 0000:02:00.0: RF_KILL bit toggled to disable radio.
[ 593.746468] iwlwifi 0000:02:00.0: RF_KILL bit toggled to disable radio.
[ 593.746781] iwlwifi 0000:02:00.0: RF_KILL bit toggled to disable radio.
[ 593.747091] iwlwifi 0000:02:00.0: RF_KILL bit toggled to disable radio.
Sometimes my laptop hangs when I try to toggle the state of the radio
devices and have to forcefully reboot it.
Reverting 522713c81e ("iwlwifi: pcie: properly reset the device") seems
to fix the problem. I haven't tried anything else since this was the
first thing I tried.
Does anyone know what's the problem with that specific commit?
I will gladly provide any additional information, just tell me what
is needed.
Regards,
Gabriele

I cannot say much to the "internals" of your problem
Just two things...
There is a new firmware for 7260 around see [0].
2nd try to pull in the new wireless-drivers.git tree, the changelog
mentions a race with rfkill on iwlwifi [1].
Have fun!

Somehow I missed it, the commit is even mentioned there.
I should have tried to pull the new changes first. I confirm that
everything works with wireless-drivers-for-davem-2014-12-26.
Thank you both for the quick replies.
