The hex codes are different, but the function names match and are in the same places. Does it have to be git bisect, or will trying the 2.6.31rc[1-9] be enough instead? The Documentation/BUG-HUNTING does not give detailed enough instructions for me to do the bisect thing. -- 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/
