It says "1/h == 5.0". It seems there is difference somewhere in FPU initialization code. And I think it should be fixed. ps. cc to me -- with best regards, Andrey Ulanov. drey@rt.mipt.ru - 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/
