Reverting commit bbbf096ea227607cbb348155eeda7af71af1a35b is reported to solve the issue [2]. bbbf096ea227607cbb348155eeda7af71af1a35b [3] is mainline commit aa3998dbeb3abce63653b7f6d4542e7dcd022590 [4] which was introduced in 6.6-rc4 which matches the original report. >> >> [1]: https://bugs.archlinux.org/task/80064 >> [2]: https://bugs.archlinux.org/task/80064#comment223100 >> [3]: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bbbf096ea227607cbb348155eeda7af71af1a35b >> [4]: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aa3998dbeb3abce63653b7f6d4542e7dcd022590 > > See Bugzilla for the full thread. I am aware of this and looking into it. The patch mentioned above seems to have introduced the issue that drives are not being stopped on shutdown with real PCs. But they are with qemu VM. So this seems to relate to ACPI shutdown as well. Not sure, looking into it. The main issue I have is that I cannot reproduce the old behavior mentioned in this case, which is, the counters not incrementing on shutdown. They do increase for me, always, even prior to the patch mentioned above.
