This regression is not only in Ubuntu. I'm running Archlinux - and for me - the regression takes also part in the Archkernel 2.6.38.x and the Liquorix Kernel 2.6.38.x. The wakeups per second raise up to 1297/second, mostly via ehci_hcd:usb1... ehci_hcd:usbx, brcm80211 and ahci interrupts, keyboard, mousepad, touchpad interrupt. The Turbo mode (2,31 GHz on my machine) uses up to 42.9% in idle mode, while except for 1% the rest goes to my 800 MHz powersaving mode. Even when being only in tty - and doing nothing, the cpu shows me that it uses 20% (instead of 1% in 2.6.32). The battery of my Compaq CQ56 has only 2 hours on Kernel 2.6.38/2.6.39, while it has 3 hours on Kernel 2.6.32.x
With kernel 2.6.32.39 I'm down on 67 wakeups per second. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
