I have a similar issue since a few days with my Lenovo T61. The laptop does not poweroff anymore. Even reboot does not. The screen is distorted and Magic SysRq do not work. I have to use the poweroff button to turn it off.
It worked perfectly since several weeks (maybe since alpha 2) and I didn't experiment too much lately so I strongly suspect a kernel issue. -- Notebook HP HDX18-1080eg does not "power off" after shutdown since kernel 2.6.31-13 https://bugs.launchpad.net/bugs/450457 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
