Title: Reboot hangs with Dell computers on 64 bits Status in “linux” package in Ubuntu: Confirmed Bug description: On xubuntu 12.04.3 64 bits, with Dell computer (7010 and some other optiplex), reboot hangs and display terminal : acpid exiting running unnatend : ... I had same problem on 32 bits 12.04, but solved by adding "acpi=force reboot=pci" in /etc/default/grub Here, on 64 bits, tried that and didn't work. I also tried every other reboot parameter, without success.
