Only reproduce once as above and didn't save dmesg. I run it more than 10 cycles just now, I can't reproduce the fail. It also fails when run automation testing, the log as below: Dmesg: <6>[ 2060.756282] [drm] stuck on render ring <6>[ 2060.799888] [drm] GPU HANG: ecode 0:0x00000000, in gem_cpu_reloc [1443], reason: Ring hung, action: reset <6>[ 2060.799893] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. <6>[ 2060.799896] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel <6>[ 2060.799898] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. <6>[ 2060.799900] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. <6>[ 2060.799903] [drm] GPU crash dump saved to /sys/class/drm/card0/error <5>[ 2060.813413] drm/i915: Resetting chip after gpu hang <6>[ 2071.773663] [drm] stuck on render ring <6>[ 2071.800593] [drm] GPU HANG: ecode 0:0x00000000, in gem_cpu_reloc [1443], reason: Ring hung, action: reset <3>[ 2071.800794] [drm:i915_set_reset_status.part.30 [i915]] *ERROR* gpu hanging too fast, banning! <5>[ 2071.810344] drm/i915: Resetting chip after gpu hang Output: command pid dev master a uid magic Test Environment check: Succeeded.
