Solved 'shutdown -p now' shutdown button restarts PC - Shut downs, after few seconds, restarts persistently after upgrade to FreeBSD-13.0

[Abraham79]

I have recently upgraded to FreeBSD-13.0 with KDE Plasma from 12.2. Before, in Gnome shutting down button worked as it is intended to be. But, after the upgrade pressing shutdown button or shutdown -p now --> system shuts down; 3-4 seconds later restarts. This is a persistent behaviour after the upgrade. I have attached dmesg output. shutdown -h now halts the system, though. Note that, shutdown works well in Devuan Linux on the same PC.

Set hw.efi.poweroff to false. See https://forums.freebsd.org/threads/shutdown-results-in-reboot.83083

Experienced a freeze/lock-in and below was the output from the virtual terminal:

drmn0: GPU HANG: ecode 6:1:0x008b8e92, in kwin_x11 [100201], hang on rcs0                                                                                                                                                                   
                                                                                     

drmn0: Resetting chip for hang on rcs0

I have to restart the system. Is this also related?

Yes. Adding hw.efi.poweroff=0 to /etc/sysctl.conf works. No restarting. But for random freezing of KDE desktop any solution? I did not have this issue in Gnome, though.

If you use the xf86-video-intel driver, try to uninstall it and use modesetting instead.

Yes. I have the xf86-video-intel installed. I have removed it. So far, not observed tear/artifacts. Will be updating on this thread.
