Freezes when screen is locked or off (Lenovo Thinkpad L450)

[Leandro Lucarella]

I have the feeling I reported this before but I can't find the original issue. I'm experiencing freezes almost every time the screen is locked, and sometimes even after the screen is off (but this happens much less often).

I had this issue before, at some point it started to fail again, and now is back, currently using 4.4.0-97-lowlatency.

I tried a mainline kernel 4.13.7-041307-lowlatency and so far is all working good, it even fixes another ongoing problem that I didn't have, then I started having again, etc. (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1575334) and some other glitches when using the dock to connect to an external monitor, that sometimes wasn't undetected after suspend.

The system feels much more stable with this kernel in general.

[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 1724513

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.

Bear in mind I've used the mainline kernel while getting the files via apport, not the faulty one.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4 stable 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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Leandro Lucarella (leandro.lucarella.sociomantic)]

Ah, sorry, I tested with the latest latest stable kernel: 4.13.7 (well, now the latest is .8, I'm already running that one, but haven't really tested it yet).

Should I really try v4.4.93?
