Still no crashes or irregular things happened ! Will let it go for a few more hours. This test is being done with the binary nvidia module loaded and bttv disabled. The next test will be nv for X instead of the binary module with bttv enabled, if crashes and such start to occur then it's very likely that the problem sits in the bttv code.
