[Kernel-packages] [Bug 1535426] Re: CPU runs at high speed after upgrade
Tried switching to 3.19 kernel - still high speed. Tried switching to intel X driver instead of modesetting: CPU still runs at high speed. The only changes I haven't backed out are: a) The Ubuntu 15.10 userland. b) The BIOS update from 1.07 to 1.10. With absolutely quiescent system, under modesetting driver, CPU will settle at 800MHz, but wiggling the mouse or outputting to an xterm causes the CPU speed to rise. Under intel driver, an apparently absolutely quiescent system seems to use more CPU than under modesetting. powertop is reporting power usage between 12 and 26 W, whereas previously with 15.04 I had power usage of 5-8W.

It "feels" as if the system is just too aggressive at ramping up CPU speed in response to demand? Is this a tuneable parameter? Really, for a desktop, something should be on a run queue for a couple of dozen ms before speed ramps up, and with a loadavg of close to zero, that shouldn't move the needle on this system? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1535426 Title: CPU runs at high speed after upgrade Status in linux package in Ubuntu: Confirmed Bug description: After a dist-upgrade from 15.04 to 15.10, moving from kernel 3.19.0-43 to 4.2.0-23, my laptop CPU runs continuously at 3GHz, and never slows down to 800MHz, as it used to.
