Priority/severity is set to default. This issue occurred only once on IGT_5106 (1 month, 2 weeks old).
Comment 3 Arek Hiler 2019-10-31 13:34:38 UTC
Seems like ther is another active thread that is waiting to toggle the port:

  def ScheduleHpdToggle(self, port_id, delay_ms, rising_edge):
    """Schedules one HPD Toggle, with a delay between the toggle.

      port_id: The ID of the video input port.
      delay_ms: Delay in milli-second before the toggle takes place.
      rising_edge: Whether the toggle should be a rising edge or a falling edge.

    if self._timer and self._timer.isAlive():
      raise InputFlowError('previous timer already enabled')

    self._timer = threading.Timer(delay_ms / 1000.0, self._RunHpdToggle,
                                  [port_id, rising_edge])

    if rising_edge:

It may be a leftover from a previous test but we do not have logs / testlist for any of the registered failures to do a popper assessment.

Anyway this is a test's/chamelium issue, so user impact is none.
