"Bug: unable to handle paging request at ..."

Hi together,

I try to figure out why my laptop hangs on shutdown. I have a really long systemd "shutdown.txt" and found something. If my pc is running some hours and I try to shutdown, it hangs a while and after I press ctrl + alt + del it continue shutting down and restarts. The following message is shown on the screen and a lot more too (without silent and some systemd kernel parameters):

How can I debug and search for the error?
