IdeaPad 5 15ARE05 with AMD CPU/GPU problems

Having a fresh IdeaPad 5 15ARE05 with AMD CPU (AMD Ryzen 7 4800U) and GPU (AMD Renoir according to the GNOME control center), here are a few problems I’ve encountered:

The backlight does not seem to be restored well and is quite bight
As I’ve switched the NVMe SSD, the new one does not seem to be quite compatible with the Linux kernel and that leads to file system errors and crashes
Sometimes when booting the touchpad and/or touchscreen are not usable. (it notices a mouse, however) Often, also the touchscreen is usable, but the touchpad is not. Rebooting usually helps…

I guess many of these issues are due to the fact that this uses a relatively recent AMD CPU/GPU…

New issue:

when restoring then device from standby, it often cannot find/use the WiFi/WLAN anymore. It claims no wifi adapter is connected IIRC or so.
