The system freezes for no apparent reason


  1. Periodically, the entire system freezes, and no buttons or panels work. At this time, the CPU load is 2-5%, the memory is used by 10-20%. Swapfs works.
    Only a hard reboot of the system helps - by holding down the shutdown key.
  2. And sometimes only the control panel hangs, restarting plasma helps (killall plasmashell && kstart5 plasmashell)

Steps to reproduce:
I did not find any dependencies for hanging both the panel and the entire system.

Info about system:

  • Laptop: Razer Blade Stealth 13 RZ09-0327 (2020 year)
  • Operating System: Manjaro Linux
  • KDE Plasma Version: 5.20.5
  • KDE Frameworks Version: 5.78.0
  • Qt Version: 5.15.2
  • Kernel Version: 5.10.7-3-MANJARO
  • OS Type: 64-bit
  • Processors: 8 × 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz
  • Memory: 15.4 Gb of RAM
  • Graphics Processors: Mesa Intel® Xe Graphics; NVIDIA GeForce GTX 1650 Ti Max-Q (4GB GDDR6 VRAM)

The system freezes (problem 1):
(journalctl -b -1 -p3)

The control panel hangs (problem 2):
(journalctl -b 0 -p3)

It might be the kernel. Version 5.10 is known to be buggy ( I had a similar problem and it went away when I switched to 5.4.
