Just a quick update - i got suspend/resume to once randomly work in LXDE environment, but after that again everytime it failed.
Then I tried using "debugging" kernel on GRUB menu, and now each time I tried suspend/resume in all environments (GNOME 3, LXDE, Cinnamon, XFCE) it worked every time as expected.
This smells like a no_console_suspend and/or whatever the new drm or i915 fast suspend/resume thing is. Are there interesting boot parameters that differ between working and non-working configurations?

Andy do you have any ideas how to disable "i915 fast suspend/resume" ?
Try i915.fastboot=0, I think. Although that seems to be the default, so I may be off-base here.
You could also try intel_iommu=on and/or intel_iommu=off -- there are historical issues there.
TBH, though, given the luks involvement, this could be some nasty plymouth interaction. Fiddling with quiet and rhgb could help.
Also, booting with no_console_suspend might give a better error message.
