Wi-Fi sometimes disappears after reboot on AMD Ryzen machine

[Konstantinos Filios]

I have an HP Omen 15 with AMD Ryzen 7 4800H CPU and GeForce GTX 1660 Ti discrete graphics card, running kubuntu 20.10 with "Ubuntu 5.8.0-41.46-generic 5.8.18" kernel and nvidia proprietery graphics drivers. One of my problems (unfortunately there are a lot) is that every now and then the laptop boots without wifi support. It seems as if the wireless controller does not even exist.

I have captured the output of dmesg and lspci in the "good" scenario, i.e. when I do have wifi (which is the most frequent case) and in the "bad" scenario, i.e. when wifi disappears.

Please note that I haven't found a way to fix this issue after boot, so I need to reboot the machine in order to get my wifi back, which most of the times works, but sometimes I need to reboot 2 or 3 times before it appears again. I haven't found a pattern yet, it seems pretty random.
