I've installed a Samsung Pro 960 SSD, which is an NVMe M.2 Gen 3.0 x 4 Solid State Drive but in Ubuntu 16.04 it freezes trying to suspend and resume. It works ok in Windows 10.

A patch https://patchwork.kernel.org/patch/10212201/ is going to fix this issue properly, it should be backported to older kernels too, so hopefully going forward your NVMe drives won't require any workarounds, it should also fix USB-C detection too

  • Thank you. I got that same link emailed to me 15 minutes ago because I was subscribed to the bug report at: bugs.launchpad.net/ubuntu/+source/linux/+bug/1655100 – WinEunuuchs2Unix Feb 12 '18 at 11:30
  • If you find any other bugzilla's or users with the same issue, please spread the word – Mike Lothian Feb 13 '18 at 12:37
  • Of course. Sharing information and helping each other is the philosophy in the Ubu-Universe. – WinEunuuchs2Unix Feb 13 '18 at 12:40
  • Finding the root cause and avoiding workarounds is the Gentoo philosophy 😜 (sorry couldn't resist) – Mike Lothian Feb 14 '18 at 14:24

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.

  • OMG. Thank you so much this seems to be a perfect workaround! I can now really use my laptop. Please fix the typo in the property name. It should be "acpiphp.disable" like you have in the sample grub line. – Doug Chamberlain Apr 3 '18 at 2:35
