Comment 57 for bug 624877

The behaviour we are seeing is dpkg hangs and never returns. As dpkg is left in the "D" state and is un-killable the only recourse is to hard reset the box (power-cycle) it. However it might be due to file-system load it can never achieve the file-system sync. I'm currently trying to come up with a reliable reproduction that doesn't involve hosing our customer boxes....
