offset not set properly in gpstime module with symetricom, possible race condition in initialization?

At the 40m the gpstime dkms modules are initializing with bad offsets. The calc_gps_offset.py script appears to be running, but the offset is not taken by the module:

Our suspicion is that there is maybe a race condition on initialization, where the script is being executed by udev before the module is fully initialized and able to accept the offset.
