Thanks. It looks most likely the freeze is a kernel bug in the 'nouveau' driver: Jun 30 09:41:31 My-System kernel: [TTM] Buffer eviction failed Jun 30 09:44:35 My-System kernel: [ cut here ] Jun 30 09:44:35 My-System kernel: Trying to vfree() bad address

Additional info... Upon invoking the freeze, Ctl-Alt-F3 sometimes brings up a terminal session on tty3. If it does, Ctl-Alt-F2 will switch back to GNOME which will remain frozen for a while, but will allow switching back and forth with the Ctl-Alt-F# keys. Running "top" on tty3 shows no

If the mouse cursor still moves then that means Xorg is still running and it was gnome-shell frozen. But we need to find out if it was just frozen or the result of a crash. Please use this command: pidof gnome-shell to check the process ID before and after the freeze and tell us if it changes.
