Sure, I've run 3 jobs:
* v5.11-rc6 as a reference, to see the original issue: https://lava.collabora.co.uk/scheduler/job/3187848
* + your debug patch: https://lava.collabora.co.uk/scheduler/job/3187849
* + the "breaking" commit reverted, passing the tests: https://lava.collabora.co.uk/scheduler/job/3187851
You can see the history of the test branch I'm using here, with the 3 revisions mentioned above:

Hope that helps, Guillaume
