Actually it's not as the kernel intel_idle driver will ignore your BIOS or UEFI settings and try and save power anyway.. We use: intel_idle.max_cstate=0 processor.max_cstate=1 as part of our kernel boot options, originally found here some time ago: http://www.mellanox.com/related-docs/prod_software/Mellanox_EN_for_Linux_User_Manual_v2_0-3_0_0.pdf Best of luck!
