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?

I'll check boot parameters and reply a bit later, but I noticed that
now that suspend/resume works it is a bit slower to suspend. On
"normal" kernel suspend is instant, when I enter "pm-suspend" or
press
suspend via GUI screen just goes black right away.
With "debugging" kernel when I issue suspend command first I see lock
screen, then screen goes black, then it blinks once more with lock
screen and then it goes off.
