Hi All,

Last couple of reboots of RPI2 have stuck when issued on
the serial console. Using the same command when su-d to
root over ssh seems to work.

The console shows:

root@www:/usr/src # shutdown -r now
Shutdown NOW!
shutdown: [pid 698]
root@www:/usr/src #                                                                                
*** FINAL System shutdown message from root@www.zefox.com ***             Stopping cron.

During reboot the serial console reports that / wasn't properly dismounted
but the system seems to recover satisfactorily.

Is this something I'm doing wrong? Latest revision to display the 
behavior is r297909.

Thanks for reading,
