cannot reboot

I installed Leap 15.1 on SSD disk in ASUS WS Z390 Pro mother board eith current BIOS version. Everything else seems to be ok, beside two troubles, one of which is, that I cannot reboot. The computer stops with a black screen, but something is hanging and it won’t reboot. Last error messages was from
Now the logfile looks like this:

Three minutes difference between 05:37 and 8:49 is the time I needed for the decission to push the reset button.
Any ideas, what could make reboot to stop ?

How long ago did you complete the 15.1 installation?

Baloo failing to exit certainly looks likely to be the problem. IceWM wouldn’t be using it. Please try logging into an IceWM session instead of Plasma, logging back out, then attempting to reboot. Do you still get a delay?

Hi, mrmazda,
yes, this has helped. I logged in in IceWM, rebooted, logged in Plasma, rebooted again is now rebooting is not hanging any more.
