On some systems (Asus), the BIOS is known to interfere with the driver

and cause read errors. The driver will retry a given number of times

and cause read errors. Or maybe the W83L785TS-S chip is simply unreliable,

we don't really know. The driver will retry a given number of times

(5 by default) and then give up, returning the old value (or 0 if

there is no old value). It seems to work well enough so that you should

not notice anything. Thanks to James Bolt for helping test this feature.
