--- Comment #27 from ish@unx.ca ---

Thought I would chime in hear and say that I'm seeing something very similar.

model        : 63
model name    : Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz
stepping    : 2

The motherboard is a MSI X99A Raider.  I did not see an option to disable over
clocking, but did disable C-states and made sure turbo boost was enabled.

On cold boot the system is fine. The cores fluctuate between 1200 and 3400 Mhz
as expected. But on a normal reboot they appear to be locked at 1200 Mhz and
never accelerate.  Additionally, apps like ps and htop show all processes with
a CPU usage of 0%.

I can increase the speed by doing a "cpupower frequency-set -g performance",
but all processes show 0% CPU usage which is not correct for the apps I'm
running.
