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). https://lore.kernel.org/linux-acpi/20221010141630.zfzi7mk7zvnmclzy@techsingu...

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:

rtc: cmos: Fix wake alarm breakage

And the third one:

commit db4e955ae333567dea02822624106c0b96a2f84f Author: Alexandre Belloni alexandre.belloni@bootlin.com Date: Tue Oct 18 22:35:11 2022 +0200

rtc: cmos: fix build on non-ACPI platforms

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

thanks,
