You are using a downstream patched tree, specifically one with further
Broadcom patches not yet upstream from my Asahi Linux tree and probably
others.

Please do not spam upstream developers with issues from downstream
trees. If you have an issue with my tree, you can report it on GitHub.
If you are using another tree, report it to its maintainer. If you can
reproduce this with *vanilla* 6.1 then you can report it upstream.
