Hello stable team and Greg,

There are 3 commits in Linus' tree for the rtc driver which should be merged against stable 6.0.y (they're already in 6.1 / 6.1.y).

Without the first two, a x86-64 machine might panic during boot (Mel saw a 50% chance of panic at boot - 5 out of 10 tries - and my experience was identical).

And after applying the first two, the kernel will not compile anymore on non ACPI platform, so you need a third one.

The first two commits:

commit 4919d3eb2ec0ee364f7e3cf2d99646c1b224fae8

All of these are in 6.0.14, can you test that to verify it all is working properly for you?
