Bug ID: 107367 Summary: [regression, bisected] Games freeze the PC with newest AMD Staging DRM Next Kernel Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: gr.muench@gmail.com QA Contact: dri-devel@lists.freedesktop.org

This reproducible all the time with Dota2 starting a benchmark with 1920x1080 and Vulkan using Phoronix test suite. Starting the benchmark makes the machine freeze and you just can hit the reset button. I also experienced the freeze with Shadow of Mordor but not all the time.

fc9a53946d9c107a36b79de3dd1a4eac43f13f3f is the first bad commit commit fc9a53946d9c107a36b79de3dd1a4eac43f13f3f Author: Junwei Zhang Jerry.Zhang@amd.com Date: Mon Jul 16 10:53:43 2018 +0800

drm/scheduler: add NULL pointer check for run queue (v2)

To check rq pointer before adding entity into it. That avoids NULL pointer access in some case.

v2: move the check to caller

Reverting the commit let the freeze go away.

--- Comment #2 from Christian König ckoenig.leichtzumerken@gmail.com --- Well that is more than just a bit strange.

Do you have an error message in dmesg that the entity was killed?

The provided patch didnt helped. And reverting the add NULL pointer check didnt helped either anymore with current git HEAD.

I did a git checkout 28756ed597d51b3ceb79c29387a40c51ea353e30 to confirm once more that the kernel worked here and confirmed that with git checkout fc9a53946d9c107a36b79de3dd1a4eac43f13f3f is the first commit that make the kernel crash. So there must be another commit after that that is making the problem worse.

Also the crash in dmesg is quite different.

Created attachment 140895 [details] Freeze with Shadow of Mordor

I applied both patches and the crash with Dota2 is fixed.

However I tried with Shadow of Mordor and the third benchmark run froze my PC again.

Completely different issue, please open a new bug report when you see that again.

This is a hardware lockup and not a NULL pointer deref in the software stack.
