Default Re: Fedora 16, GTX 550Ti, random X hangs, "Attempted to yield the CPU..."

The only error logged in /var/log/messages is the "Attempted to yield the CPU..." one, no "Xid" or "fell off the bus" or anything. /var/log/X/X.0.log contains messages like:

I don't think we're seeing the exact same issue here.
