While probeing PLL information via radeon_get_pllinfo(), it does a "gettimeofday(); do_something(); gettimeofday();" type sequence explicitly with interrupts disabled, so ends up with a zero measurement which then results in a bunch of divisions by zero.
We should decide whether gettimeofday() can be expected to advance with interrupts disabled, or that clocksource_jiffies is simply invalid because of this behavior. - 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/
