Reboot of 5.2.1

[Doug Hardie]

I am testing 5.2.1 in preperation for moving production servers 
eventually from 4.6 to 5.x.  Most of the issues I have figured out, but 
there is one that I cannot get to work - shutdown -r now.  Rebooting 
dies consistently.  With the GENERIC kernel I get the message:

Rebooting...
Keyboard reset did not work, attempting CPU shutdown

In NOTES is a dexcription of BROKEN_KEYBOARD_RESET so I added that and 
rebuilt the kernel.  Now all I get is the Rebooting... line and nothing 
more.  Granted the system I am using for testing is not at all like the 
production hardware, but rebooting worked fine on 4.6 with this system. 
  I am very reluctant to convert any production systems unless I can be 
sure they can successfully be rebooted without having a person on-site. 
  These machines are all unattended and quite far away.  Is there a 
workaround for this issue?
