After unmingling the problem went away. I suspect that the 64/32 div resulted in a >32 bit result which is a fault. This was deep in monotonic_clock. I would rather change to clock_monotonic (i.e. xtime+offset+walltomonotonic) and work that code patch. monotonic_clock is just the wrong thing for this work. > > tglx > > > - > 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/ > -- George Anzinger george@mvista.com HRT (High-res-timers): http://sourceforge.net/projects/high-res-timers/ - 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/
