I'm still seeing this periodically, previous to today it happened on April 24th. Doesn't matter what I'm doing the video will freeze however the cursor will still move. Only option is to SSH in to the system from my tablet and do a reboot. Note: This has been going on since Sept 13, 2014. There could be as little as a few hours between freezes or as much as 30 or more days.
