Public bug reported:
I have an I7-6850k machine Asus X99-A motherboard, 128GB memory with
Artful 17.10 installed. The official clock speed of this processor is
3.6 Ghz, I have it clocked at 4.3 Ghz, however, if I install the intel-
microcode package, the machine ignores the BIOS settings and reverts to
3.6 Ghz. Since this package is necessary from a security perspective
I'm stuck with either being insecure or losing an enormous amount of
performance.
