This is on kernel 2.6.8 using the bttv driver, and appears easily reproducible. Anyone any ideas? thanks, Lennert - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
