Comment 6 for bug 328440

I get something like this frequently while doing a shutdown cycle with the 2.6.28 kernel, including up to 2.6.28-11-generic#37 amd64.

The symptoms are:

1. I choose restart or shutdown.

2. The usplash screen shows and shutdown seems to progress normally.

3. Near the end, the screen changes and either goes blank or it shows the end of a fault message.

4. If I control-alt-delete, it continues shutdown and restarts.

The log might show something like the attached.

I used to think it was something to do with the nvidia module, because it seemed to always do this if I did a suspend/resume cycle and then tried to reboot, but not if I just rebooted without a suspend/resume cycle; then I added nvidia to the list of modules to remove by adding it to /etc/pm/config.d/modules and for a while this seemed to fix things. It isn't working any more though.

Currently, it does it with all of the nvidia 180.37, 180.41, and 185.13 drivers.
