https://bugzilla.kernel.org/show_bug.cgi?id=80651 Bug ID: 80651 Summary: [intel_pstate] pstate settings are lost during suspend/resume cycle Product: Power Management Version: 2.5 Kernel Version: 3.15.6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq Assignee: cpufreq@xxxxxxxxxxxxxxx Reporter: liquid.acid@xxxxxxx Regression: No Created attachment 143431 --> https://bugzilla.kernel.org/attachment.cgi?id=143431&action=edit dmesg output Hello, the patches that went into 3.15.6 made the intel_pstate driver finally useable for me. At least as long as I don't suspend/resume the system. After resume the multiplicator is locked to the highest one. I have to change min_perf_pct and max_perf_pct to some other values and then back to restore the behaviour before the suspend. CPU is a Haswell / i7-4700HQ.
