    Hi,

    I am afraid not.

    Overkill but correct. +mpf would be even better

    Good

    No.

    /sys/kernel/debug/dynamic_debug/control holds the collection of the
    messages that may be triggered, but it does not tell you which messages
    are triggered and in which order. The triggered messages end up
    in syslog. So you would use 'dmesg'
    I am afraid you redid the test correctly and then threw away the
    result.
    Could you redo it and just attach the output of dmesg?

    Sorry
    Oliver
