System not powering off

First of all: thank you folks so much for your answers!

at around February 20 and still ongoing I have the same issue on a Dell Laptop, see below for details. I am not sure where to start reporting. Basically the system is not powering off, no matter if “reboot”, “power off” or “standby” target should be reached. So when the computer goes stand-by (for example triggered by inactivity), it will not power off (fan continuous running, display on). Then i have to force a power off by pressing the power button for a few seconds. it will restart just fine, as all systems and mounts are down at this point.

i was able to go back to kernel version 6.6.* at grub where it was working just fine. but while skipping some kernel version, i retried w/o success.

also during this period the intel webcam stopped working. and at some point (may be not serious) i discovered a rather unclear issue with un-signed kernel modules regarding ipu6 and/or v4l2 could not load during boot. but i am not sure about a relation to this issue with powering off.

as to read in a maybe related thread, i also looked for “denied” term in journalctl:

unfortunately the latest kernel update now removed the older 6.6.* kernel that was working as expected.

You should be able to re-download and install an older kernel. Some methods of (re)installing specific kernel versions can be found in Fedora’s documentation.

As for the inability to fully power off your system. I think I’ve seen others report similar problems lately. It is likely that you’ll just have to wait for the kernel devs to resolve the problem. Though it is possible that you could have caused such a problem by misconfiguring your BIOS or by adding something like noacpi or acpi=off. Also, be sure your firmware is up to date.

thank you for the hint. I never heard of koji before.

i search there, but those 6.6.* version i found have been deleted at koji. instead of searching for a non-deleted i was able to go back to Linux 6.5.6-300.fc39.x86_64 with dnf. powering off is working this way, but leaving me a bit unhappy about newer kernel versions.

FWIW, I think the bug you are seeing might be related to the “Put CPUs into INIT on shutdown” patch that was reverted for the 6.5 kernel series. This issue has been reported here before.

There is also an open bug report with people reporting that various iterations of the patch do or do not work with their systems.

https://bugzilla.redhat.com/show_bug.cgi?id=2241279

My guess is that the kernel devs are still working on that code. You might want to chime in on that bug report with your results and follow it to get alerts about the latest fixes.
