I'm not really sure this should be posted here, but anyway the problem is this:

The process of shuting or rebooting gets "paused" in some tasks...and it can take a few minutes to complete it. This doesn't always happen, and it doesnt always happen on the same task. No errors or other extra info is shown.

And it gets really strange because if i press any key on the keyboard it moves on in a few seconds.

Any idea what this might be or where i should start looking for clues?

This is on openSuSE11 64bit btw.
