[mythtv-users] mythbuntu stops working for no reason

the entire machine does lock up, but sometimes i'm able to hit escape and
get it to go back to the menu.  other times i just pull the plug.  and after
the first time it stops working, it never starts again.  not even after a
reboot.

here are the logs.
