My motherboard has a nforce 790i SLI chipset and the bug affects me since Ubuntu 12.04 release (kernel 3.2) : my USB devices are still powered when I shutdown the machine. However, unplugging everything except the mouse and the keyboard makes them powering off.
3.0.0-16 to latest kernels are concerned. The diff between 3.0.0-15 and 3.0.0-16 is this commit : http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c61875977458637226ab093a35d200f2d5789787 Reverting it in a recompiled kernel may resolve the issue for concerned motherboards/chipsets. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/936190 Title: nForce 590 USB power regression in 3.0.0-16 and 3.2.0-24 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/936190/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
