One of the differences between 4.7 and 4.8 is the maximum supported firmware version. 4.8 was bumped from version 21 to version 24. linux-firmware has version 21 and 22 for your device.

Try deleting /usr/lib/firmware/iwlwifi-8000C-22.ucode and reboot, 4.8 will load version 21 instead of 22 then.

After deleting /usr/lib/firmware/iwlwifi-8000C-22.ucode and rebooting the wireless network controller started to work again.

Same problem here with the 7260 card, just filed a report. Isn't the ucode version 17 the current one?
Comment by Jan de Groot (JGC) - Thursday, 27 October 2016, 09:12 GMT
Kernel probably needs some fixes to work with the new firmware:
http://git.kernel.org/cgit/linux/kernel/git/iwlwifi/iwlwifi-fixes.git/log/

Guess the last iwlwifi fixes from there are not yet in 4.8.x.

Comment by Tobias Kornmayer (t0b1as) - Saturday, 12 November 2016, 07:16 GMT
Hey guys, sorry but as it turns out I also have the 8260 intel card. I guess it would use /usr/lib/firmware/iwlwifi-8260-24.ucode so why delete /usr/lib/firmware/iwlwifi-8000C-22.ucode? Any news concerning this bug?

It has been working fine for me on every iteration since 4.8.6, if I remember correctly. Still works fine on 4.8.11:

~ dmesg | grep -i iwlwifi
[ 9.199916] iwlwifi 0000:3a:00.0: enabling device (0000 -> 0002)
[ 9.204689] iwlwifi 0000:3a:00.0: Direct firmware load for iwlwifi-8000C-24.ucode failed with error -2
[ 9.204796] iwlwifi 0000:3a:00.0: Direct firmware load for iwlwifi-8000C-23.ucode failed with error -2

[ 9.245694] iwlwifi 0000:3a:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208

I believe linux-firmware is still missing versions > 22 upstreaam.

Can we close this bug?
Comment by Tobias Kornmayer (t0b1as) - Monday, 05 December 2016, 13:12 GMT
Well, actually I needed to rename the 8000C-22.ucode to something else, so that the kernel picks the next version to make it work. I have Revision 3a of the chipset, maybe that's the reason that it sometimes works and sometimes not.

The problem is still present with linux-firmware 20161205.91ddce4-1 and linux 4.8.12-1

My 8260 works fine. Some errors present forever, but module forks fine.

Is this still relevant?

I'm still not have any issues with my 8260.

The problem has been fixed with the new version of the firmware: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-8000C-31.ucode
