Hi all, I've got a new Asus XG-DLS dual Xeon motherboard with two Pentium II 450MHz Xeon procs and if I compile in SMP support I get the following problem: After bootup, if I start top and set the delay seconds (s) to 0(zero) the cpu load for the top process goes all the way up, and then after a little while it goes all the way down and everything has the same cpu utilization of 0.00%. Then if I start systat vmstat 1, it says: The alternate system clock has died! Reverting to ``pigs'' display. I can start systat -vmstat 1 without any problems if I do not 'stress' the cpu or if I do it right after bootup. I am running the latest stable, but I also had the problem with 3.1-RELEASE. I tried using the MP1.1 spec setting in my bios to no avail. Any help or suggestions would be appreciated. It might be of importance to note that the CPU line does not show the MHz of the chip. Thanks in advance for any help. Marko marko@globix.net here is my dmesg and mptable output. Copyright (c) 1992-1999 FreeBSD Inc.
