FYI - I tried with the 11.11 release and see the same thing. It looks 
like u-boot is never getting into the shell, so the commands we send it 
get lost. I'll dig in more when I get some time.

Here's some output with some debug messages I added:

<LAVA_DISPATCHER>2012-04-10 08:43:20 PM INFO: Perform soft reboot the system
