Thx for the report. I CCed Damien and Niklas (and the regressions list), maybe they have an idea. If they do not reply you most likely need to perform a bisection to raise interest in your report. And FWIW, there is one important info that afaics is missing from your report: If the latest mainline kernel (e.g. 6.11) still affected?
