Okay, here's compilation of "dmesg | grep -i udev && udevadm
monitor && lsblk" on linux-4.4.221 vs linux-5.4.39. You can check
my attachment here because I can't explain it by words (I'm not
english native speaker anyway, which makes it so difficult to
explain it for me).

It's a weak machine, it took appropriately 2 hours to just compiling
linux kernel. I need to think twice too because electricity is expensive here.
