Thx for the report, but the harsh reality is: nearly no developer will
see your initial report, as you just sent it to LKML, which nearly
nobody ready. I CCed a few lists, which might help. But that is
unlikely, as this could be cause by all sorts of changes. Which is why
we likely need a bisection (
https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html
) from somebody affected to make some progress here.

That being said: there are a few EFI changes in there that in a case
like this are a suspect. I CCed the developer, maybe something rings a bell.

Ciao, Thorsten

This is a known issue, and will be fixed in the next 6.8.y release.
