Yes, it's a freeze and not just graphical. Resuming from a good kernel
makes OpenSSH available remotely even with no input at the lock screen.
However, resuming from a bad kernel when the screen is black, OpenSSH is
unavailable remotely. This suggests that the OS has hung altogether in
the black
In my case, (my original report at

...and it made no difference when booting
I note some others have had failures booting 4.15 even though a recent
mainline based on 4.15 allowed me to resume my desktop from hibernation
successfully.
Probably goes without saying, but saying it anyway. If you don't use the
same kernel for boot and for resume, I speculate that could create
Note that using Kernel Mainline (4.15) also seems to sidestep this bug,
unless that's a false negative for some other reason (e.g. kernel
mainline has an implicitly different load configuration, so isn't
creating the conditions for the bug).
I was guided to triage against kernel mainline
