ACPI log messages about ACPI group/action undefined: xx

This week I upgraded the RAM of my current system, because it sometimes froze while watching videos on youtube. But after the update, I recognized that less often, but sometimes my system froze again. Also waiting did not solve the problem, so I looked into my journalctl and saw a lot of lines

 Mai 23 21:28:23 PaulsHP root[5756]: ACPI group/action undefined: processor / LNXCPU:00
Mai 23 21:28:23 PaulsHP root[5758]: ACPI group/action undefined: processor / LNXCPU:01

Mai 23 21:28:25 PaulsHP root[5789]: ACPI group/action undefined: processor / LNXCPU:07
 

. The journal was full of them, sometimes i scrolled throuh 10000s of lines of about a half hour logs. Also not all logs are about ac
I also recognize this events for PowerButton or VolumnButton pressed-events.

Mai 23 21:29:13 PaulsHP root[5952]: PowerButton pressed
Mai 23 21:29:13 PaulsHP root[5954]: ACPI action undefined: LNXPWRBN:00
 

But the strangest thing is, that if I do acpi_listen, all events get listed correctly

 ac_adapter ACPI0003:00 00000080 00000000
processor LNXCPU:00 00000081 00000000
processor LNXCPU:01 00000081 00000000
processor LNXCPU:02 00000081 00000000
processor LNXCPU:03 00000081 00000000
processor LNXCPU:04 00000081 00000000
processor LNXCPU:05 00000081 00000000
processor LNXCPU:06 00000081 00000000

battery PNP0C0A:00 00000081 00000001
battery PNP0C0A:00 00000080 00000001
button/power PBTN 00000080 00000000
button/power LNXPWRBN:00 00000080 00000006
battery PNP0C0A:00 00000080 00000001
battery PNP0C0A:00 00000081 00000001
ac_adapter ACPI0003:00 00000080 00000000
battery PNP0C0A:00 00000081 00000001
battery PNP0C0A:00 00000080 00000001

My problem is, that currently, every time i plug in the ac, my log gets filled with this messages and my processors tend to have really high usage, sometimes freezing until I restart the system. When I use my system unplugged, everything looks fine. 
As a side note,I didn't changed any line in my acpi-handler in directory /etc/acpi.  Can you tell me, if this problem is co-related to the log and if so, how i could solve this?
