Sorry haven't been able to test in a while, I just tried
kernel.x86_64 4.8.14-200.fc24 last night both with and without "acpi=off"
and with acpi in the default setting the system would go to sleep but I
was able to wake the system up and log in normally. When I set acpi to
off the system didn't go to sleep but when the graphics display started up
I got a grey screen but never presented with a login prompt.
The other item I noticed is that when the system started it initial boot
(file system encryption is enabled) the graphics screen that comes up
asking for my password the screen is reduce to about 1/2 the normal size.
Laptop is a T440P the grub line I'm using is -
GRUB_CMDLINE_LINUX=" rd.lvm.lv=fedora_laptop/root
rd.luks.uuid=luks-533e7156-775d-48f6-abbd-90f14f31303d
rd.lvm.lv=fedora_laptop/swap rhgb quiet i915.enable_rc6=7
i915.enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 acpi=off"
I'm now suspect of the i915 driver but I don't know for sure.
I suggest dropping all the i915 options and go with kernel defaults while troubleshooting this. It might also be useful to add no_console_suspend ignore_loglevel when troubleshooting suspend problems.
