The system is an AMD K6/350 in an ASUS P5A ATX 512K ALI motherboard with
256MB of RAM.

Kernel is a straight compilation from source with no modifications to the
GENERIC config file.

>Description:

Multiple system time calls such as gettimeofday show that system time is
advancing at approximately double with wall clock rate.  Output of
test described below produces:

Tue Mar 11 09:25:12 PST 2003
Tue Mar 11 09:25:22 PST 2003

Doubling the sleep value to 10 seconds produces:

Tue Mar 11 09:27:08 PST 2003
Tue Mar 11 09:27:28 PST 2003

Verification of the sleep time to a wristwatch shows the sleep time to be
approximately correct.

>How-To-Repeat:

Run the following from a command line shell such as /bin/sh:
date; sleep 5; date	
	
>Fix:
