Sorry, last post got html infected! Hello, I've been trying to enable PC8 on my Haswell i7-4600M Notebook but i'm not sure if it is working properly. During idle states (No X running) 915_pc8_status tells me that PC8 seems to be disabled: Requirements met: no GPU idle: no Disable count: 3 IRQs disabled: no Enabled: no Is this supposed to be right? Powertop 2.5 reports that Package C-States never go above pc3 while Core C7-HSW and GPU RC6 states are always reached with > 90%.
