 Can you please show us the output of:
 
        top -t
        lockstat -o foo.txt sleep 5
        vmstat -e
 
 Also, please break into the debugger (Ctrl-Alt-Esc with a keyboard) and
 capture the output of:
 
        mach cpu 3
        bt
 
 You can return with 'c'. It's good to have a camera / camera phone handy for
 the last one if you are not using a serial console.
 
 Thanks,
 Andrew
