I have a dual-proc server that I've recently decided to overhaul. It's an Asus A7M266-D motherboard. It has been running with dual Athlon MP 1800+s, RedHat and BIOS rev 1003 for at least a year with no real problems. First I decided to change the OS to Gentoo. I built the system with no problem and built a custom kernel based on linux 2.6.7-gentoo-r11. Everything was working great. Then I changed out the procs and went with dual Athlon MP 2800+s. To support these, I needed to (according to Asus's website) upgrade the BIOS to 1011.002 or higher. (Latest is 1011.003, so that's what I used.) Now, when I boot to this custom kernel I get about 2 seconds into the boot process before the system starts spewing constant "APIC error on CPU0: 04(04)" messages. It stops booting at that point. I've done a little research and it seems that I'm supposed to do a couple of things: 1. Disable "MPS 1.4 Support" in the BIOS. 2. pass the kernel "noapic" as a parameter. I've done both of these and I STILL get the APIC messages. (Which leads me to suspect the "noapic" isn't working or I'm doing it wrong at the very least.) My line from the grub.conf is: kernel /kernel-2.6.7-gentoo-r11-smp root=/dev/hda3 noapic acpi=off apm=off I've build another custom kernel where the only difference is that SMP is disabled. Sure enough, that works like a champ, but with only the single CPU. I've searched through the kernel "make menuconfig" menus and can't see that I'm missing anything. In fact, I can't even FIND "APIC" options unless I disable SMP... I'm just about out of ideas here... Any suggestions?
