I found a bug that Linuxkpi resume and suspend code never run when I run
acpiconf -s 3

I just put pr_debug into suspend and resume function in linux_pci.c file and
put drm debug information to amdgpu driver

The Linuxkpi’s suspend and resume was not called after running acpiconf -s 3
the bug caused the drm suspend and resume was not called.

I have already set company.linuxkpi.debug=1 in loader.conf

I did not find that debug information  in /var/log/messages
