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@xxxxxxxxxxxxxxxxxxx/ 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 Author: Rafael J.
