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
