Bug Description

After playing Gurumin: A Monstrous Adventure for some time, the system crashed in an unrecoverable way. REISUB was required to get some logs.

The syslog contains the following:

This crash seems to be easy to reproduce. I made an Apitrace of the part of Gurumin with the scene that caused the first crash and let it replaying endlessly. After 1h30min, the system crashed again.

The apitrace can be obtained from: https://mega.nz/file/8thHlYpa#_HBCUsIifUnD8R3K2U6v--BWg8noez_Fn7KazWrrGRg

A warning to those that want to play Gurumin: what was traced here can be considered mild spoilers.

I just tested the Xubuntu Beta ISO and, from it, I was able to reproduce the system crash.

Unfortunately I was unable to obtain any logs, as sshd was no longer responsive and it was a live system.

I'm not sure this is good or bad news, but glxgears also crashes the system:

The crash is still present with 5.4.0-24. The attached file has syslog, Xorg.0.log and xsession-errors.

I noticed there are two workarounds for this:

1) Set the intel Xorg session instead of modesetting;
2) Change vblank_mode parameter from xfwm4: auto or glx will trigger this crash, xpresent or off won't.

Which is unexpected to me, as it seems there is nothing related to i915. However, the computer really doesn't crash after this commit. The bisect log is below. Some of the kernels crash my computer in seconds:

This bug is fixed by upstream commit da42104f589d979bbe402703fd836cec60befae1: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=da42104f589d979bbe402703fd836cec60befae1

It looks like that commit was *supposed* to be backported to 5.4 ("Cc: <email address hidden> # v5.4+"), but the i915 maintainers didn't do it, so we'll need to backport it ourselves.
