3.11.0-* (starting from 3.11.0-0) -> not ok, see bug description

3.10.0-* -> ok but wifi is *sometime* turned off at boot (I have to check "Enable Wifi network" in NM)
In this case I see a "RF_KILL bit toggled to disable radio" in dmesg with no visible error.
The fact that this is random is quite strange.

3.9.0-* -> work perfectly (Wifi already connected when lightdm appears
on screen)


So the big thing seems to be with 3.11 (at least >= rc4, which is 3.11.0-0 AFAIK).


Now trying to narrow the scope with mainline kernels:
v3.11-rc1-saucy -> It works!
v3.11-rc2-saucy -> It works!
v3.11-rc3-saucy -> It works!
v3.11-rc4-saucy -> FAIL

So the problem is between rc3 and rc4.

Now it's going to be more complicated because this laptop is not suited for building kernels. It will take forever.
(I have a more powerful desktop, but it's not running Saucy)

Could someone help me find a potential faulty commit in order to speed up the bisecting process?
Thanks.

Title:
  Wifi and bluetooth disabled at boot and hard to re-enable

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Network Manager says either "Device not ready" or "wireless is disabled by hardware switch" (it depends).
  Enabling Bluetooth in the control-center just enable it for like half a second and then it's switched off again.

  I have a combined hardware button for both Wifi and Bluetooth, it's red when it's disabled and blue when enabled.
  In this case it stays red even when I repeatedly press it (though the Bluetooth setting panel reliably indicate when it is hardware disabled, so I guess the color is only related to software lock).

  I manage to make it work again after playing with "rfkill
  [block|unblock] all" and messing around with network manager
  (disabling network and then re-enabling it...). I usually need around
  5 minutes to make it work.

  I did not have this problem on Raring. I had it on saucy with the 3.10
  kernel but it seems to be worse with 3.11 (I need to mess around for
  more time in order to make it work again).

  Feel free to ask if you need any additional test.
