[igt-dev] [CI i-g-t] tests/perf_pmu: Try to repro GL #6806

[Ashutosh Dixit]

CI ONLY, PLEASE DON'T REVIEW

Try to repro GL #6806 and see what is really happening there since it could
not be reproduced locally. Also see if the
https://patchwork.freedesktop.org/series/110574/ will fix the issue.

Bug: https://gitlab.freedesktop.org/drm/intel/-/issues/6806
