Saw this again and was able to shell into the laptop and investigate. The machine is not locked up. I can strace X and see that it still reads keyboard and mouse events. However killing off the clients doesn't change the display. Killing off X hangs the machine, requiring a sysrq reboot. This is with latest Jaunty amd64.
