Unfortunately the i915 RC6 patch was dropped with commit 371de6e4e0042adf4f9b54c414154f57414ddd37 because the RC6 fix still seems to make some systems freeze and as yet we've not got a reliable list of hardware that fails with rc6. The current recommended solution is to enable rc6 using i915.i915_enable_rc6=1 for hardware that doesn't lock up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/913886 Title: Power consumption regression (12.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/913886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
