Stuff before&after makes less sense, and I'm misssing the function exit code which should follow. Propably the add %rip does something fancy out-of-line. In other news we have an obj on the pinned list with gtt_space = NULL. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/906086 Title: [arrandale] kernel OOPS setting external monitor to a higher resolution To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/906086/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
