That's strange! Is it the same for the other one? I just double
checked on the slight chance I had an alias causing problems etc, but
that wasn't the case:

$ 'dmesg'|'grep' ENERGY
[ 0.010557] ENERGY_PERF_BIAS: Set to 'normal', was 'performance'
ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8)
$ dmesg --version && grep --version
dmesg from util-linux 2.25.2
grep (GNU grep) 2.20

OK, I will resubmit with a new description if needed.
Would you agree that info is a more suitable log level than warn for
this message? Even notice seemed too much, as it isn't a 'significant
condition'


Thanks,
Steven
