ACPI off (failed)
Modify grub configuration as above to turn off ACPI (Advanced Configuration and Power Interface) at boot.
GRUB_CMDLINE_LINUX_DEFAULT="acpi=off"
shutdown umount script (failed)
Add the pre-stop script to /etc/init/dbus.conf before 'exec'
sudo gedit /etc/init/dbus.conf
pre-stop script trap "TERM signal" TERM /bin/umount -a -t cifs -f -l trap - TERM end script
Update ATI driver (failed)
For ATI Radeon HD 5700 Series, go to www.ati.com to download latest.
sudo sh ./ati-driver-installer-11-6-x86.x86_64.run --buildpkg Ubuntu/natty sudo dpkg -i fglrx*.deb
Notes
At shutdown or restart the computer may or may not hang.
- doing a shutdown from the desktop will logout instead most of the times (9 out of 10) and show the login screen
- shutting down does not complete, sometimes a trace shows up that mentions FGLRX (ATI proprietary video driver), it does not timeout, it keeps hanging indefinitely
- seems to be happening more often when a truecrypt partition is mounted

- "I finally managed to fix the problem by removing the acpi=off from my grub kernel options... I had a look at '/etc/init.d/halt' script, I noticed that in case of shutdown, it called the /etc/init.d/ups-monitor which was not installed..."

- "created an init.d script to run at shutdown. All the script does is remove the snd_hda_intel module at shutdown (rmmod snd-hda-intel) and things work smoothly. See this thread for more detail: http://ubuntuforums.org/showthread.php?t=500268 "
