Public bug reported:

Suspend was working on ubuntu 18.04 with kernel 4.15.0-128.

After upgrade to ubuntu 20.04, suspend is not working. The device is on
black screen, fully powered and not responding any longer.

I can still boot the old kernel 4.15.0-128 from ubuntu 18.04, suspend is
working with this kernel!

I tested kernel 5.4.0-60 and 5.8.0-36 from hwe. With both kernels,
suspend is broken on my older  device with Core2Duo.
