rebuilt system to fresh install of natty and found with a combination of 'acpi=force' and also having rt2800pci blacklisted things worked for me, thought i would do more testing using the proposed kernel worked but i wanted to work out more what was happening with the system.
here are the workaround steps which worked for me; 1. edit "/etc/default/grub" change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="acpi=force" 2. Update grub # update-grub 3. Blacklist rt2800pci # echo "blacklist rt2800pci" | sudotee -a /etc/modprobe.d/blacklist.conf restart machine and things worked, hopefully this helps others out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762203 Title: Computer is not turned off at shutdown -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
