It could be many things. I would check bad UVs first though. If your using imported geometry that doesn't have UVs and then you try to use a bump map, or other texture, referencing non-existant UVs you can get rendering exceptions. Other than that I would have to see the scene to track down whats going wrong. I believe Micha uncovered some SSS issues that caused similar problems as well - but I haven't heard back from CG about any results from checking into that problem.
