	Pentium III 850 MHz, Intel i815 Chipset
	
>Description:
	I installed FreeBSD 7.0 Release on an old Pentium III with 
	i815 Chipset. I noticed that date shows the wrong time. I
	correct this with ntpdate. Short time later time is wrong
	again, clock is far in the future. I booted the system with 
	acpi off. Clock ist to fast to, but not so extrem like with 
	acpi on. This Problem happens only with this Hardware. Maybe 
	its a problem with the i815 Chipset. OpenBSD has on the same 
	Hardware, the same Problem. See:
	http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=5796

>How-To-Repeat:
	Install FreeBSD 7.0 on a Motherboard with i815 Chipset. Watch the clock.
