Maybe you can figure out why the readings are off by 4%. I suspect that someone has set a clock divider wrong when programming the chip. For example setting the divider for a 25Mhz clock when the clock is actually 26Mhz would cause the error you are seeing. Or they just made a mistake in computing the divisor. It is probably a bug in the BIOS of your laptop. If that's the case you could add a quirk in the system boot code to fix the register setting. -- Jon Smirl jonsmirl@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
