I want to report that I got the same bug under Ubuntu 16.04 with hardware enablement stack. The bug came with a recent update of the linux-generic-hwe, I now have 4.8.0.48.20 and I am affected. I also have an XPS 9550 with the 512GB Samsung NVMe. Was the APST support backported to 4.8?
For the moment my workaround is using the old 4.4 kernel, but I will try the kernel parameters as well...

That patch has a quirk for certain 256GB Samsung drives found in Dell laptops that do not behave well when APST is enabled. I am experiencing the same symptoms with the same model laptop except with a 512GB Samsung. Prior to manually disabling APST the drive would die and system would go down in flames with I/O errors within 20 to 40 minutes of boot. $ sudo nvme list Node SN Model Namespace Usage Format FW Rev ---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- -------- /dev/nvme0n1 ************** PM951 NVMe SAMSUNG 512GB 1 500.20 GB / 512.11 GB 512 B + 0 B BXV76D0Q ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: linux-image-4.10.0-14-generic 4.10.0-14.16 ProcVersionSignature: Ubuntu 4.10.0-14.16-generic 4.10.3 Uname: Linux 4.10.0-14-generic x86_64 ApportVersion: 2.20.4-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ajclayton 3305 F.... pulseaudio CurrentDesktop: Unity:Unity7 Date: Fri Mar 31 09:42:38 2017 InstallationDate: Installed on 2012-09-08 (1665 days ago) InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) MachineType: Dell Inc.
