What smbios are you using? Are you certain your profile is correct? The "Attempt to re-register power management" is usually an error seen with incorrect configuration on Haswell systems (using XCPM in kernel).
Maybe caused by your use of SleepEnabler. SleepEnabler is a bad idea.
That is normal. Post the DSDT if you need help with the errors.
I would work on cleaning up your power management situation, getting rid of SleepEnabler and any other non-recommended kexts you may have installed. Do a fresh install if necessary.
