The freeze up occurs where nothing works on MP i.e. the screen is frozen and nothing will get it out of that state i.e. remote or keyboard. I can sometimes go to the Task Manager and kill off MP to get back in, but often I have to reboot. It's almost like something is hogging the machine.
Create a new support report with logs and specs, if something is screwing up only after resume hopefully that will show the culprit.
Use start menu\logs collector, start from step 1 and upload using forums advanced + feature.
