[arch-general] Hibernation not working

[Peter Nabbefeld]

Hello,

since some time, hibernation does not work, dmesg contains following 
messages:

[  738.404244] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type 
mismatch - Found [Buffer], ACPI requires [Package] (20160422/nsarguments-95)

Some time ago, when I closed my laptop, Linux automatically hibernated, 
now it does not. As my laptop becomes really warm and I don't want to 
stress my display, I'm using this rarely, so I cannot tell, since when 
hibernation doesn't work :-/

Kind regartds
