The /sys/class/drm/card0/error report.
Playing Portal 2 for a few minutes causes the following symptoms:
- Audio loops last ~0.5 seconds for ~30 seconds, and then the game crashes
- The log includes the line:
"intel_do_flush_locked failed: Input/output error"
- dmesg includes the following message:
[ 192.808861] [drm] GPU HANG: ecode 9:0:0x85dffffb, in portal2_linux , reason: Hang on render ring, action: reset
[ 192.808863] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 192.808864] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 192.808865] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 192.808866] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

[ 192.809191] [drm] GuC firmware load skipped

This prompted me to file this bug report. Attached is the GPU crash dump. There are some indications (https://github.com/ValveSoftware/portal2/issues/278) that this issue may only be present in versions of mesa after a certain point.
Thank you for your help, and let me know if I can provide further diagnostic assistance.
