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 kaslr acpiphp.disable=1 pcie_aspm=off nloglevel=3 udev.log-priority=3"
Your options will be different but add the option acpiphp.disable=1 between the double quotes.
Save the file and run sudo update-grub
Reboot and then suspend and resume will work, unless it’s a different problem.
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.
