Public bug reported:
Ever since upgrading from Bionic to Focal, my machine frequently
(multiple times per week) fails to wake up from suspend with the default
5.4 kernel (linux-image-generic).
When booting the 4.15 kernel from Bionic that I still have installed
(linux-image-4.15.0-46-generic), suspend and wake-up works reliably
again.
The symptoms of the failure to wake up are that the machine powers up
(fans, LEDs), but the screen stays black. Num lock LED on the keyboard
is ON and cannot be toggled. The Machine cannot be pinged.
After hard-resetting the machine, the last entry in journalctl from the
previous boot is "kernel: PM: suspend entry (deep)".
