I'm seeing behaviour on rebooting a Raspberry Pi Linux system which is
stopping the PPS signal getting through to NTP. It seems that the GPS
device does not emit any pulses on the PPS line for some time after it
has been powered up. This I understand and it's the time taken for a
good enough lock to be acquired.
However, it seems that if the PPS part of the kernel hasn't seen a
transition, it does not create the pps device at least until the first
transition is seen. The delay seems to be some 133 seconds here:
Does this seem possible, and how might it be fixed?
