Hi Christopher, I found the culprit and can confirm this is not a bug with the kernel 4.4.0.38. I attached a Sony PlayTV usb dvb tuner (dib0700) a little while ago. I use it with TVHeadend which is installed as a background service. After disconnecting it the system suspend/resume was working perfectly again.
To fix and allow me to keep the dvb adapter connected I had to create a pre-suspend/post-resume script in /lib/systemd/system-sleep/ directory that would first stop the TVHeadend service then unload the dvb module prior to suspend and the inverse upon waking. /etc/init.d/tvheadend stop modprobe -r dvb_usb_dib0700 While the fix works it's a bit strange that the livecd had no issue suspending with the usb dvb adapter attached since dmesg clearly showed it was able to unload the dvb adapter. Maybe it's the fact that TVHeadend was not loaded in the livecd and accessing the tuners??? Not sure... Either way, I have a solution so happy for you to close this bug report.

When I `pm-suspend` the computer remains powered on but is completely unresponsive. There is no signal going to my monitor and I can't enter a tty shell or ctrl+alt+del to restart. I'm forced to press the the physical reset button. This happens every time I perform a suspend. I can shutdown and reboot at the moment. I really wish DSDT loading was still available, I could have attempted to fix this myself with a patched bios (if a bung ACPI call is the culprit).
