Hi Zachary,
I wrote for the same issue yesterday. A little more research online
revealed that this is a known issue with dual core chips and the
proprietary nvidia driver that gutsy has in the achieve. I think it has
something to do with a conflict in the SMP kernel switch causing kernel
locks.
At any rate the fix I read about involved manually installing a
different driver from the Nvidia web site. This seemed to work for some
people. I found that the install failed for me and I have not had time
to sort it out yet. Let me know if it works for you.
