I've recently updated to kernel: Linux desktop 4.10.8-200.fc25.x86_64 #1 SMP Fri Mar 31 13:20:22 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux with Fedora 25. I did a few reboots without power cycle with c-states disabled, which is how I last left my bios configured. Running htop showed CPU percentages after each boot, i7z showed cores hitting max mhz. I then reset my bios to factory default, which enables c-state. And did a few non-power cycle reboots, again seeing expected behaviour with the cores. I did not have to power cycle this time to get full speed. I'll keep monitoring it, but is it possible a kernel update could have fixed it? ===> /sys/class/dmi/id/ ./product_serial =====> Default string ./bios_vendor =====> American Megatrends Inc. ./product_version =====> 5.0 ./chassis_asset_tag =====> Default string ./chassis_serial =====> Default string ./board_vendor =====> MSI ./board_asset_tag =====> To be filled by O.E.M. ./board_version =====> 5.0 ./power/runtime_suspended_time =====> 0 ./power/autosuspend_delay_ms =====> ./power/runtime_active_time =====> 0 ./power/control =====> auto ./power/runtime_status =====> unsupported ./chassis_vendor =====> MSI ./modalias =====> dmi:bvnAmericanMegatrendsInc.:bvrP.50:bd07/19/2016:svnMSI:pnMS-7885:pvr5.0:rvnMSI:rnX99ARAIDER(MS-7885):rvr5.0:cvnMSI:ct3:cvr5.0: ./product_uuid =====> AAAAAAAA-AAAA-AAAA-AAAA-D8CB8AEDA146 ./bios_version =====> P.50 ./sys_vendor =====> MSI ./board_serial =====> To be filled by O.E.M. ./chassis_version =====> 5.0 ./chassis_type =====> 3 ./uevent =====> MODALIAS=dmi:bvnAmericanMegatrendsInc.:bvrP.50:bd07/19/2016:svnMSI:pnMS-7885:pvr5.0:rvnMSI:rnX99ARAIDER(MS-7885):rvr5.0:cvnMSI:ct3:cvr5.0: ./product_name =====> MS-7885 ./bios_date =====> 07/19/2016 ./board_name =====> X99A RAIDER (MS-7885) -- You are receiving this mail because: You are the assignee for the bug.
