I'am testing Ubuntu 12.04 Beta 1 (3.2.0-18-generic and Mainlinekernel 3.3-rc6) and shutdown does not work. If i tray to shutdown or restart ther is the Ubuntu-Logo with the wording and the whites and the Orange points but it freezes. If it is frozen ctrl+alt+del or ctrl+alt+F1 show no effect. The hard drive turns off but the CPU and the display will continue. I have tried the following terminal commands, but the result is always the same. sudo shutdown -h now sudo shutdown -P now sudo halt sudo poweroff sudo reboot The problem occurs on a Acer TravelMate 8473T (use UEFI, not BIOS) This is my first Report on bugzilla.kernel.org and i am sorry that I can give no further information. This system forgets that there was a problem, because the hard drive turns off. This problem does not occur under Ubuntu 11.10 (3.0.0-generic).
