For what it's worth, I had a similar sounding problem on a Dell Latitude E7470 on Ubuntu 20.04 (upgraded from 18.04). Suspend would work okay, but most of the time resume would just end up rebooting, immediately. I noticed a Bluetooth error in the dmesg output, so I disabled Bluetooth, both in Linux and in the BIOS. Now resume always works. I'm running the vanilla Kernel (5.4.0-34-generic).
