Specifically: /sys/class/rtc/rtc0/wakealarm Without this sysfs file, the rtcwake and sleepgraph tools no longer function properly (and probably all tools that use the RTC through sysfs). I've tested on 10 machines so far and this occurs on all of them regardless of the specific hardware. The issue is in this patch set for the rtc subsystem. If I remove this commit and rebuild, the issue goes away. I'm in the process of bisecting further. commit b7270c69a36efc61ed6ebd31a8a458f354a6edc0 Merge: 4ce1b97949cb e5f12a398371 Author: Linus Torvalds Date: Fri Oct 14 18:36:42 2022 -0700 I've opened a bugzilla issue here: https://bugzilla.kernel.org/show_bug.cgi?id=3D216600
