Is there any reason why you used CLOCK_TICK_RATE in some places and
1193182 in others ??? I can understand your using the number in the
definition of CLOCK_TICK_RATE but not in the other cases.
If I'm reading it correctly, the result is a collection of bugs on the
AMD ELAN system as that uses a different frequency (at least, according
to the last but one hunk in your patch)...
Best wishes from Riley.
