Around 1-2 weeks ago I noticed that my system became unstable resulting that applications couldn't be started anymore but I was still able to move the mouse cursor so it was not a full system freeze.

Today this issue happened again and only partly processes froze (for example I could still open a terminal with top but not htop and closing processes worked not very well) so I was able to make a look at dmesg. Mainly this message got spammed several times:

Also sometimes I have seen additionally these 2 messages:
