Loading iwlwifi produces the following messages to dmesg. Trying to
bring the wifi interface up also fails.

I'm on Arch Linux, and linux-firmware is built from commit d877533.
With older firmware (commit f1b95fe), it works with this in dmesg
output:

[Tue Oct 23 07:28:51 2018] iwlwifi 0000:3a:00.0: enabling device (0000 -> 0002)

Kernel version is 4.18.16, the machine is a Lenovo T470s. I'm happy to
provide more info!

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.

Hi!

It was actually 2 weeks ago when I noticed the problem, and I've used
the older firmware since then. I just had in the bottom of my
"backlog" to report this somewhere. I now tested again with the newer
firmware, and this time it seems to work!

My machine is not dual boot, but I've had several warm and cold boots
in between. Maybe this had an effect? Dunno, but now it works.

Thanks, and sorry for the noise.

Petri
