Hello Gabriel,
the uniprocessor version uses an optimization at the reader side:
#if defined(RTEMS_SMP)
} while (gen == 0 || gen != th->th_generation);
#else
} while (gen != th->th_generation);
#endif
This is possible since the windup happens with interrupts disabled. I
guess you need this optimization somewhere in the PPS/NTP code.
Could you please add the details to the commit message and not the cover
letter. The cover letter is not committed.
Could you please have a look at:

It would be also good to have a test case for the problem you are trying
to fix. The PPS/NTP code is a bit complicated and the test coverage of
this area is far below the score average.
