Boot log kernel 4.13.5-200

Description of problem:
Just installed kernel-4.13.5-200.fc26.x86_64 as an update, and after reboot wireless networking is gone.
The kernel seems to crash in the iwlwifi module as seen in the attached boot log.


Version-Release number of selected component (if applicable):
kernel-4.13.5-200.fc26.x86_64

Using kernel-4.13.4-200.fc26.x86_64 shows no issues whatsoever.

Hey Josep,

Would you be willing to perform a git bisect to find the offending commit?

Comment 2 Josep 2017-10-16 09:14:41 UTC
Hi Jeremy,
I can try bisecting the kernel, could you point me to the git repository used for fedora's kernels? Thanks!

As a side note, just mention that I have another laptop (also asus) that uses the same wifi driver, but doesn't show any problems.

Comment 3 Stanislaw Gruszka 2017-10-16 11:28:06 UTC
Before bisection I would check if updating the firmware does solve the problem.

Josep, please download latest firmware blob from 
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-8000C-31.ucode
and put into /lib/firmware/ directory . Then restart machine and see if issue still happen.

Comment 4 Josep 2017-10-16 11:47:47 UTC
Hi,

I just tried the new firmware, and it seems to solve the problem, I am not seeing any issues or crashes so far. The firmware works for the older kernel too (4.13.4-200).

thanks!

Great!
