In bug 1683266 :dholbert was able to run mozregression and found it was regressed by bug 1661528. It seems likely that the nvidia driver does not correctly handle persistently mapped buffers after suspend/resume. This bug almost certainly has the same cause, this signature is during update_texture_cache() whereas the other one is when uploading to VBO textures.
