Kernel 4.13.0-26.29~16.04.2 Causing Crash

Upgraded kernel to 4.13.0-26.29~16.04.2 and Cinnamon crashed while display was way off. As you can see in the system specs below, I booted into kernel 4.10 and all is well

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1742603

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Before testing mainline, can you see if this bug exists in 4.13.0-21, which does not have the PTI patches? It can be downloaded from:

https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/13870500

Notes, you need to install both the linux-image and linux-image-extra .deb packages to test the kernel.

Same issue with kernel 4.13.0-21

[Benedict Brown (benedictbrown1)]

I am seeing the same problem I think. The system crashes on boot in kernel 4.13.0-26-generic in Ubuntu , but boots fine on 4.10.0=42-generic. I have a Dell Precision T3600 with a Xeon E5-1620 CPU. ecause the system doesn't boot (even in recovery mode), I cannot run apport-bug to file detailed logs. I can upload a screenshot of the crash if necessary.

What I can report from memory is that the crash comes from dereferencing a NULL. On my most recent attempt, the last [Ok] message before the crash related to the sound card, and another one comes up after the error message related to the keyboard. Then everything freezes. I have no reason to believe that either of these modules is actually the culprit.

Can you test the mainline kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc8

[Benedict Brown (benedictbrown1)]

My colleague who handles IT for the department and has been seeing this on multiple computers reports the following:

I tried the mainline kernel 4.15-rc8 , no joy. Still getting the NULL pointer Oops error.

[Joseph Salisbury (jsalisbury)]

I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.

Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug:

v4.11 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11
v4.12 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12
v4.13 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13

You don't have to test every kernel, just up until the kernel that first has this bug.

Thanks in advance!
