    Hi Rio,

    this happens on a perfector "healthy" / normal Kernel boot. If certain dependencies for a given driver are not in place at time of probe the Kernel will try to probe this module again later, that's called deferred probe. Only if the "deferred probe" fails several times this will result in an error with a given driver/module.

    Hi AD:

    Yes, I know, but I dont know how to resolve this 1 by 1...:(.

    I already tried everything.

    9.2 SDK wont give me those errors.

    Hi Rio,

    as per email discussion, please share a complete(!) boot log of booting your SDK v10-based image on the custom HW Including U-Boot and everything. Then, also provide the output of `ls -al /lib/modules/*`.

    Also, we need to stick to using either E2E (preferred) or email to discuss this (and other) concerns; otherwise it becomes confusing and creates too much overhead.

    Regards, Andreas

    Hi AD:

    I forced the SD card working as Legacy mode by setting this, now, the problem is resolved.

    Hi Rio,

    I'm glad you found a workaround to get this to boot; however it should not be needed. As per separate email discussion there have been MMC-tuning related changes in SDK v10.0 that might be causing a regression here; something we need to urgently investigate and fix, if needed.

    Let's leave this E2E thread open so we can document any findings for knowledge sharing purposes.

    Regards, Andreas
