I hard-rebooted the first time as the screen locked up due to multiple alarms popping up in the morning. Trying to stop one caused a screen lock-up - a segmentation fault (according to the logs). Successive hard-reboots are thus merely as a result of my new-found curiosity and hence this post. It never did this before, although I'm also on new hardware, so it may be as a result of that. And hence asking if others have witnessed said issue.
