    I noticed this error on my Orco device used for tests many moons ago,
    but I could never find out what led to this error case, it wasn't
    deterministic and didn't impact the audio quality. All I could do is
    rate_limit it... If we have an A vs. B situation it'd be really helpful
    to diagnose further.

    Is there really a causality between the changes from Hans and this PLL
    unlock error? Are you 100% sure this was not present in the previous
    install you used (4.18.14 as mentioned earlier in the thread)?

    Thanks

    -Pierre
