I checked the diff between e91976c0 and 7596afd4 and it is very very small.
Is your machine dual boot?
A few users have reported a race between BT firmware load and Wifi
firmware load. They also reported that booting in Windows, and then
shutting down in Windows helps to boot Linux properly.
If the above is not applicable, please open a bug in
bugzilla.kernel.org and add linuxwifi@intel.com to the bug.
Thank you.
