I'm running Kubuntu 20.04 with Linux 5.11 on Lenovo Ideapad Gaming 3 15ARH05.
Hibernation mostly works without problems, but sometimes the system freezes after resume. I can see the mouse pointer, but I can't move it. Switching TTYs doesn't work too.
Here's a kernel log I was able to get:

I tried to search for this swap issue, but all I was able to get was that the RAM is corrupt. It's a new laptop, and this issue has been happening since I bought it, so it's unlikely.
Note that this laptop had problems with Linux before, like no brightness and touchpad not working. Linux 5.8 added support for this new AMD CPU (AMD Ryzen 5 4600H) and Linux 5.11 fixed the touchpad. Linux 5.12 and above break the touchpad again.
