I am also experiencing this same issue on an Acer Aspire Slim 5. I installed Ubuntu 20.04 server edition and then Mate-desktop on top of that. It seems that I only experience this issue when I do not have ethernet plugged in. With ethernet plugged in the system boots just fine into the window manager. I get the same dmesg output as above. I will try and collect all the relevant information and post it soon.
