Hello! And all the best for 2021.

I am quite new to this, so please excuse if I am not getting it right.

I am sleeping with music by night. Since I changed to kernel 5.10.4 my system cannot be "woken up" from display standby any more. I have a two minutes timer of inactivity to turn my display off. Everything works as expected when the display is in the standby state for a couple of hours. But when it is in this state for over 6 hours it cannot be woken up again. The screen stays black, the display stays in standby mode.

In the background it seems the system works fine. I can change the volume of the still running music, can even alt-F4 close the music player (Audacious).

I am running Ubuntu 20.04.1 LTS linux 5.10.4-051004-generic Kernel 5.10.4

Only some of the methods shown below this posts worked on my system for gathering more data, ubuntu-bug linux brought an error about a non existent package, cat /proc/version_sig... brought an error about file or folder not found.

lspci-vnvn.log is attached.

System specs:
AMD 2400G using APU for display output, mesa drivers libegl-mesa 21.0~git2012200730.f9ceab~oibaf~f
X370 chipset mainboard (biostar)
16GB RAM DDR4 2933

Please let me know if you need more data and how to gather it. Thank you!
