So, sharing my experience
I solved this (apparently) turned off serial port on bios.
I can wake form sleep normally
I overlooked this setting and had lots of freezing problems updating an older Gigabyte H77 to Catalina. Thanks a lot!

I was so excited to find this easy fix for this problem, but then I was frustrated to see that my serial ports were already disabled!!!! However, after installing the kext from freituk, wake from sleep seems to be working again. Thanks!
