That's good news, thanks for testing!

I've pushed out an updated series against v6.6 earlier today in case
anyone wants something specifically against v6.6, but I don't think
there is any pressing reason to re-test. The only ACPI change
between the two is:

9b311b7313d6 ACPI: NFIT: Install Notify() handler before getting NFIT table

and the only arm64 changes are in dts files. Nothing significant in
kernel/ and nothing in drivers/base/.

So I think at this point, I will pause waiting for 6.7-rc1 (which
I'll do an updated patch set, since it will include changes queued
up) and hopefully followed by Rafael's comments. Maybe James will
also have some time to work on this again.
