I'm running Ubuntu Focal and I have 15gigs of Ram and 20G of swap space.
Partition: ID-1: / size: 437.52 GiB used: 47.14 GiB (10.8%) fs: ext4 dev: /dev/sda5
ID-2: swap-1 size: 19.53 GiB used: 0 KiB (0.0%) fs: swap dev: /dev/sda6
I've tried adding acpi=noirq to my grub boot options but it didn't work and it ended up disabling my keyboard.
When I type sudo pm-hibernate and turn the computer back on it starts up normally.
Is there something else I could try?
