Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 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.

I am also seeing the same crash when running Ubuntu 17.10 with the Gnome desktop using the xwayland compositor. This manifests in a slightly different way. It does not require the screen to turn off. It can occur randomly at any time, usually when the system is idle. I am currently get one or two crashes a day. But the system can sometimes run for a day without a crash. For details see bug #1746232 which problem be reassigned to this package.

Oops I meant to say "which probably should be reassigned to this package."
