Running a Lenovo Yoga 720 with kernel 4.14, I pulled the:
git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git 
tags/iwlwifi-fw-2017-11-03

to try the new fw version 34 on my:
3f:00.0 Network controller [0280]: Intel Corporation Wireless 8265 / 
8275 [8086:24fd] (rev 78)

And got this firmware crash and no wifi working:
(for reference firmware version 31.560484.0 from same git pull works)

Yes, this was a screw up on my side regarding the FW API.  We have a
bugzilla and a patch to fix it already (on my comment #6):

https://bugzilla.kernel.org/show_bug.cgi?id=197591#c6

I'll try to get this into the first stable release for 4.14.

Sorry for the trouble and thanks for reporting!

Thanks. That patch fixed the crash here too :)
I'm now happily using v34 here

I'll queue it up in Mageia distro kernel too before landing the new 
firmwares there...
