Kernel NULL pointer dereference with linux 4.10

Hello,

I recently intended to update my archlinux distro with pacman -Syu, but I was not able to boot anymore.
I reverted back to the version 4.9.11 of linux, and now it is working again.

I managed to find the error responsible for the crash, here is the log:

(please ignore my machine name ^^)

Do you have any idea of what is happening ? I found no one facing a similar error hmm
I am running archlinux on a Lenovo x250 laptop.

Thanks in advance,

Re: Kernel NULL pointer dereference with linux 4.10

Welcome to the arch linux forums groud.  From the thread title "Kernel NULL pointer dereference with linux 4.11 & 4.10" you reference 4.10 the last mainline release upstream from kernel.org and 4.11 currently on release candidate 6 upstream from kernel.org.

avril 11 19:31:03 SWAGGY kernel: CPU: 3 PID: 1661 Comm: Xorg Tainted: G     U          4.10.8-1-ARCH #1

The log mentions 4.10.8 so do you mean 4.10.9 contains the issue 4.9.11, does not contain the issue and you have not tested any of the releases between those two?

Re: Kernel NULL pointer dereference with linux 4.10

Hello,

Thanks you.

Oops, you are right, I was a little bit confused with all those numbers smile.
The problem happens with th 4.10.* version of the kernel, but not with the 4.9.* ones. Sorry for the mistake.

Re: Kernel NULL pointer dereference with linux 4.10

Probably it's just i915 borked (again)™.  Might need/want to go upstream.

Re: Kernel NULL pointer dereference with linux 4.10

Before filing a bug report upstream please read all of the following:
https://01.org/linuxgraphics/documentat … eport-bugs
https://www.kernel.org/doc/html/latest/ … -bugs.html
https://wiki.archlinux.org/index.php/Bisecting_bugs

If you are not confident in kernel building, patching, bisecting and seeing the bug report through to completion please do not report it upstream.
Also please do not report it to the arch bugtracker instead see Reporting_bug_guidelines.

I'm a Fedora user, but I have the very same problem.
Thanks for the links and inputs.
