Chris, do you think it is the same issue as Bug 102575 ? If it is, then this patch series might fix it: https://patchwork.freedesktop.org/series/47043/

According to Chris, this should not be the same issue.

Hasn't occurred again in a week though. High?

Last occurred 1 week, 3 days / 357 runs ago

Still seen only once. Moving to high.

Still only once in 2+ weeks. Can we close it?

Occurred once, 1847 runs ago. Closing.

First and last seen on CI_DRM_5090_13 (3 months, 3 weeks / 2252 runs ago), which is a BAT run which means this runs ~7 times per day.

The CI Bug Log issue associated to this bug has been archived.

New failures matching the above filters will not be associated to this bug anymore.
