I had a shutdown attempt of the computer this afternoon where it didn't shut down, and hung on the shutdown with the line after the localhost login displayed and remained displayed so I could write it down. Here is what I saw: localhost login: [ 9211, 806671] [ T1] reboot; Power down
That is really the last message before kernel turns off the system. It sounds like kernel issue.
I'm curious. I plymouth is installed, even with plymouth.enable=0, is there any part of a plymouth library loaded by the boot-loader or kernel? The reason I ask is I've run into the shutdown hang ever since Leap 42.X on this HP laptop, but uninstalling plymouth completely has cured the issue 100% of the time. My thought, may be wrong, but if the boot-loader or loads part of plymouth, even though the kernel parameter plymouth.enable=0 is set, could whatever address holds the part of plymouth be responsible for the hang? That's the only thing I can think of that would make any difference between using "plymouth.enable=0", or "rpm -e plymouth-dracut ... ..." Thankfully this is a laptop, because unreliable shutdown/reboot kills the ability to remote admin a box quicker than anything else... -- David C. Rankin, J.D.,P.E.
