I am having the exact same problem Bionic 18.04 x64 system kernel 4.15.0-34-generic . I have just had too hard reboot the system to regain control after waiting a hour of thrashing. All input devices are locked. As my system has too remain up all day this issue needs to be resolved to avoid HDD damage.
