It is said that the crashes cease when the `nopentium' option is used, so it does appear that something is up.
I does seem that the nVidia driver is usually involved.

-rmap is still young. I did some heavy stress testing on it a couple of days ago and it was rock-solid, and performed well.

Yup. But don't forget about the `nopentium' observations.
