Did a quick run.. and thought of testing power management and found
that CPUFreq for my platforms are broken in v3.18-rc7 and my scripts
broke (so much for my cronjob testing daily boot... now I gotta add
some PM test as well.. Sigh..) anyways.. just boot log..

will try to first try and save a bit of cpufreq and reinstate my
scripts and once you post based on 3.19-rc1, will do a retest..
