Title:
  [krillin] Second slot not detected on reboot

Status in the base for Ubuntu mobile products:
  Fix Released
Status in ofono package in Ubuntu:
  Fix Released

Bug description:
  The second slot is not detected some times on reboot in krillin after
  latest ofono update. It appears as "Disconnected" in the network
  indicator.

  This is regression that occurs due to the introduction of a new
  query_modem_type that was introduced with the latest arale changes:

  https://github.com/alfonsosanchezbeato/ofono/commit/83cb2dcf4d2387c38f08b5c8e0ca80b806e51c2b

  Prior to this change, the mtk plugin only created a few atoms, and
  registered for some RIL events.  With the change, it sends a
  QUERY_MODEM_TYPE request which will fail if the radio actually hasn't
  gone online.  Note, a valid response from a POWER_ON request doesn't
  indicate that the radio is actually online, so a race existed between
  the actual power transition and the post_online method sending the
  query.

  Detected in vivid-proposed image #94
