NVMe SSD suspend/resume is a know bug

This problem has been reported on Launchpad and ArchLinux. The solution is to edit /etc/default/grub with sudo powers and find the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpiphp.disable=1"

Your options will be different but add the option acpihp.disable=1 between the double quotes.

Save the file then reboot. Now suspend and resume will work.

What does acpiphp.disable=1 do?

According to the kernel developer in 2013 this disables ACPI hot-plugging. However that doesn’t mean hot-plugging is disabled on your machine. For example, replugging the USB cord to your Android phone brings up Nautilus to view files as it should. Also power cycling a second TV connected to your laptop via USB-C ThunderBolt 3 to Displayport to HDMI adapter reorganizes windows across workspaces as it should.

Proposed permanent fix

A few days ago a permanent fix was proposed in kernel 4.15.0-23 by someone who is probably a Ubuntu Developer.
