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.

Expected results: All open applications should run normally: occasional slowdown for page faults are tolerable but the observed behaviour is not. Actual results: Several times per day my computer will become completely unresponsive apart from high hard disk activity. Once it enters this state: it will not recover without a hard reset regardless of any time waited or input given. On one occasion I have tested it by leaving it thrashing for 12 hours, at the end of which there was no evidence of progress. This behaviour was not observed when running Ubuntu 16.04 on the same computer and swap settings.
