I'd like to perform a kernel bisect to identify the commit that caused this regression. Would it be possible for you to assist by testing some kernels? If so, we need to first identify the kernel version that introduce the regression, then we can bisect down to the actual commit.
Can you start by testing the following kernels: v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/ v3.5-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc1-quantal/ ** Bug watch added: Linux Kernel Bug Tracker #44851 http://bugzilla.kernel.org/show_bug.cgi?id=44851 ** Also affects: linux via http://bugzilla.kernel.org/show_bug.cgi?id=44851 Importance: Unknown Status: Unknown ** Tags added: performing-bisect -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024507 Title: 12.10 quantal boots to black screen on iMac To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1024507/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
