Just to keep track, you can remove my earlier report (https://bugzilla.kernel.org/show_bug.cgi?id=217864 <https://bugzilla.kernel.org/show_bug.cgi?id=217864>) from regzbot. I've split out the boot/shutdown/reboot part from there into this new one as that was still reproducible on default distro Kernels.

Hopefully someone else can find the root cause of the problem. My systemd version is: 254.1, and I also use dbus 1.14.10 and dbus-broker 33.r35.g2220a84 which was configured with -D linux-4-17=true.

Do you have test environment with similar configurations so that
you can bisect there?

> Some other observations: It was very odd to notice that with 6.5.* local h264 video playback with mpv did not work any longer - mpv did not even open the files (it works fine with the older Kernel); the monitor refresh rate was set to 165 Hz (instead of the manually set 120 Hz) and opening of the task bar, Dolphin or attaching files to an E-mail took a lot longer to bring up the dialog than with the older Kernel. Hitting the power button still could successfully turn off the PC though, but clicking on the usual shutdown/reboot Plasma Desktop icons did not seem to work, at least not reliably in every case.

In that case, can you attach mpv output?

Thanks.
