Comment 107 for bug 944772

Shutdown does not work for me on 32bit 'precise'.

For me issue was resolved via switching from proprietary nvidia drivers ver.295.40 to nouveau driver.

When using nvidia drivers shutdown issue occured when I run some video in VLC. I was unable to switch to tty1 (just blank screen) -- in this case system hang at shutdown. If I was still able to go to tty1 then pc shuts down perfectly (for example immediately after logging in).

I tried to switch to older nvidia drivers like 275.x: seems to work but I decided to reinstall ubuntu from scratch. Now shutdown works for me ok.

HW: Dell Vostro 1500, core 2 duo, 3Gb ram, ssd ocz agility 2, nvidia geforce GS 8400M.
