I'm not sure if I'm seeing exactly this bug, but my desktop (old i7, 64bit) also freezes froze up on me several times since upgrade to 16.04. Looks like it's just the X server that gets borked. Every time it happened I had music playing in the browser (Google music). Display goes dark, mouse and keyboard are unresponsive, music keeps playing. Logging in via SSH and killing X sort of fixed it, but after logging back in my analogue sound output is gone (I see in Control Center > Sound only built-in digital one). Everything's back to normal after reboot.
