I had a problem like this once with an Asus P2B-D and changing those modes seemed to help. My understanding of the MPS versions is just that MPS 1.4 has a stricter set of rules than 1.0. Again something I know nothing about. -----Original Message----- From: Kevin Turner [mailto:kevin@freedomhosting.com] Sent: Tuesday, October 09, 2001 11:28 AM To: freebsd-isp@freebsd.org Subject: Strange SMP Problem. Hello, Just recently I noticed one of my webservers was not showing two CPU's when doing a top. I checked dmesg, and noticed the following: FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000 io0 (APIC): apic id: 1, version: 0x00170011, at 0xfec00000 cpu1 is not showing up. The machine is running 4.2-STABLE, and has been working perfectly for quite some time. I haven't made any kernel changes or any other changes I can think of. Any ideas?
