Bug description:
  baremetal nodes are failing to boot for me:

  Note the gap between up and status checking is only 200ms (from IPMI return to status check) but in that interval this hardware doesn't toggle to on.

  After the deploy fails, a manual check with
  ipmitool -I lanplus -H 10.10.16.40 -U Administrator -P <password> chassis power status
  returns
  Chassis Power is on
