Fix Command:

Problems:
stop reached target shutdown
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
if not work change to 

GRUB_CMDLINE_LINUX="reboot=b intremap=no_x2apic_optout acpi_osi=Linux initcall_blacklist=pcc_init"

stop starting show plymouth boot screen
f configuring the boot loader that way : 
yast

• System
  
  • Boot Loader
    
    • Boot Loader Options
      
      • Optional Command Line Parameter

Replace splash=silent by splash=verbose

Right now I can think of the following options:
- Change the kernel boot option "splash=silent" to "splash=verbose"
- Disable plymouth by adding "plymouth.enable=0" to the kernel boot options
- uninstall plymouth completely
