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 screen case and it's not just a display issue.
