I am getting frequent DRM hangs while playing Cities: Skylines from Steam

[Clint Byrum]

It happens during normal gameplay. Have tried reducing settings. Seems like a legitimate driver bug. The program crashes, but X does not.

[Daniel van Vugt (vanvugt)]

Looks like it's the Intel i915 kernel module crashing. So that's the 'linux' kernel package.

[Brad Figg (brad-figg)]

This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

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 v4.9 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.

Hello!

This game never worked properly. I installed it and it had these hangs starting immediately. It got better after I turned graphics detail _way_ down, but it still happens every 20 - 45 minutes of game play.

I installed the mainline build from today, and it did not help:

I will attach the error file mentioned and mark the bug private (in case the memory references has sensitive information).

[Clint Byrum (clint-fewbar)]

Launchpad must have changed since I last did this. It says the bug won't be visible by you even though I subscribed you. Let me know if that error file will help and I'll send it somewhere, but I'm concerned it may have sensitive information from system RAM in it.

[Joseph Salisbury (jsalisbury)]

Can you also give the latest DRM nightly kernel a test? It is available from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2016-12-06/

I'm installing it now. The crash is less frequent with 4.9 (have gone
2 hours now without it), so it may take me a few days to confirm it
doesn't happen anymore.

[Clint Byrum (clint-fewbar)]

I was able to play about 12 hours of the game without a crash. So things definitely improved. But eventually it happened again.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

[Clint Byrum (clint-fewbar)]

I'll try and do that some time this week. Thanks Joseph.
