Do you experience this when booting to runlevel 3 (ie, without gnome active)? Do you experience this if booting with i915.i915_enable_fbc=0 on the kernel command line? > Do you experience this when booting to runlevel 3 (ie, without gnome active)? Everything seems fine in init 3 > Do you experience this if booting with i915.i915_enable_fbc=0 on the kernel command line? Don't know if I did it right but here's how I did what you asked: 1. Pressed 'e' in grub 2. Appended "i915.i915_enable_fbc=0" to the line beginning with "linux [...]" 3. Pressed F10 to boot => Still 40-60 Interrupts when idle (In reply to comment #2) > > Do you experience this when booting to runlevel 3 (ie, without gnome active)? > Everything seems fine in init 3 Then you're almost certainly seeing the sync-to-vblank interrupt. Which means you're drawing 40-60 frames a second for some reason. If you ssh into the machine while it's idle (fresh login, no apps running) and run powertop, do you see the same interrupt load? If so this is probably a bug in the base gnome session causing excessive redraws. If not, you're probably simply seeing the interrupt load from running powertop itself. The number of interrupts I see via ssh is significantly lower than inside the gnome session itself. Where do we go from here? "significantly lower" means ~0-15. This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
