Public bug reported: I had a fresh installation of Ubuntu-18.04. From the beginning suspend was failing spuriously. When I looked up in Google, I was suggested to upgrade my kernel as the provided kernel 4.15 was buggy. So I compiled the kernel from source and upgraded to 5.04. The problem still persisted. Having GRUB_CMDLINE_LINUX_DEFAULT="acpi_sleep=nonvs" in the file /etc/default/grub and running sudo update-grub does not change anything. Finally I have narrowed down the problem to calling sudo pm- suspend directly. The command works perfectly fine until a few suspend- wakeup cycles have passed. After a few cycle, the screen blanks out and the system does not go to sleep. Nothing responds and I have to do a hard reboot after which everything works the same.
