I will provide logs soon! what do you want exactly?

One apparent regression I have noticed is that "sensors" reports CPU
power usage at idle is now steady at 101W vs the usual 50W (which used
to be 40 before a kernel update) while I am not sure if it is accurate
as the cpu temp doesn't reach high levels expected for such wattage it
does have one bad effect in that Turbo 2 no longer works...and even
before this update with my v4.6 to get Turbo 1 on all cores as AMD
advertises I must use "tpc -psmax 1"[1] which brings up the sensors
reported TDP to 125W whereas normally it wouldn't work due to maxing out
at 115W and 3.35ghz rather than T1 3.5ghz the TDP determining when the
CPU enters full turbo 1.

I use Turbo 2 to obtain better performance on non-multithreaded games so
this is disappointing but I will investigate further.
