Bug Description

After a screen lock, the screen hangs, with the attached stack dump in dmesg.

I've seen multiple bug reports with similar effect, but the workaround has been "video=SVIDEO-1:d" as boot parameters, but this does not affect my case. Also, the other reports, such as https://bugs.freedesktop.org/show_bug.cgi?id=93782, includes 'intel_tv_detect' which mine does not.

Here's a partial dmesg log from a locked screen to the hang with drm:debug=0xe.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.12 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.

This was actually on Elementary OS, but I've tried with a 4.2 kernel where the problem does not exist.

I've now also tries 4.12.0-041200rc1 and this input hang does not occur. Booting with this kernel does render my WiFi inoperable, though. I suppose that might happen when trying non-offical kernels, right?
