Heya Folks,

Since updating to Fedora 11 I run into a problem with nouveau.

When I've been away, on returning there's no response to either keyboard or
mouse input, so I can't get out of the xscreensaver. Sometimes this happens
while I'm working, in which case the screen gets garbled, in those cases the
mouse still works, but the keyboard doesn't.

In both cases I need to restart the machine remotely.

Today I finally got something that might be helpful in /var/log/messages:

The first message is from this morning when I unplugged my PDA.
The remainder are when I powered on my monitor upon my return.

Mazzel,
