Description Markus Mertens 2017-06-13 09:38:01 CEST

Description of problem:

To be able to use an "Intel Corporation Wireless 8260" wifi device it was neccessary until kernel 4.9.30 to rename any newer firmware (ucode-file) than version 21:

cd /usr/lib/firmware
mv iwlwifi-8000C-22.ucode iwlwifi-8000C-22.bak
mv iwlwifi-8000C-27.ucode iwlwifi-8000C-27.bak

Since the latest official kernel upgrade (4.9.31) even this trick does not work any more.

Thanks for the bug report. Please give the output of the command:

      rfkill --list


and also attach log.txt that is the result of running, as root:

     journalctl -ab > log.txt

(Assigning this bug to the kernel and drivers maintainers)

Ah, you got hit by an upstream patch that stated older api firmwares should not be supported on 4.9 series (fixing a commit that landed in 4.9-rc1+), but apparently in your case you still need older api firmwares...

I will fix it tomorrow when I build a 4.9.32 based kernel

(In reply to Markus Mertens from comment #3)
> # rfkill --list 

Sorry, I should have asked for the output of 

     rfkill list

It is no longer needed, though, since Thomas already knows how to fix the problem :-)

Comment 6 Thomas Backlund 2017-06-15 07:15:59 CEST

 kernel-4.9.32-1.mga6 is out, allowing to use older api firmwares again

Status: NEW => RESOLVED
Resolution: (none) => FIXED

Comment 7 Markus Mertens 2017-06-15 14:32:05 CEST

Yes, I can confirm that wifi is working again! Hopefully the older api firmwares will be supported much longer because the actual brand new HP ZBooks still use this Intel device (Intel Corporation Wireless 8260)...
