Public bug reported: System apparently correctly suspends (in various ways - from gnome menu, with pm-suspend on bash, with echo ... > /sys/power/pm_test) and resumes bringing up X, gnome, consoles, mouse, keyboard - but not the nvme SSD. Since I have the OS on that, no command relying on disk files is recognized, and I'm forced to hard power off by long press on power button.
Usually at resume it is possible to switch to consoles (Ctrl-Alt-Fn), which display a lot of messages about i/o errors and failing journal writes. bash may be still alive on either X or consoles, but it will understand only internal commands and thus it is not of much help even for shutting down the system cleanly. Tried to add the following options in various combinations on the GRUB_CMDLINE_LINUX at no avail: acpiphp.disable=1 nvme_core.default_ps_max_latency_us=0 acpi_osi=! \"acpi_osi=Windows 2015\" The only grub helping is mem_sleep_default=shallow but that is a bit of no brainer as it suspends to S2 preventing S3. The same effect have echo s2idle > /sys/power/mem_sleep and echo freeze > /sys/power/state As for what is said in https://wiki.ubuntu.com/DebuggingKernelSuspend, I've tried pm-tracing but wasn't able to understand enough information from dmesg hash matches. As for debugging, all echos to /sys/power/pm_test resume correctly but the last, echo none, which causes the problem. The issue does not seem graphics related as X wakes up correctly (initially; it may crash later), and as the problem is identical even with no X (telinit 3). Hope all necessary debug information is automatically added, if not please ask.
