I'm having an odd interaction between APIC and my motherboard's (a Shuttle sk41) built-in USB and ethernet controllers. If I enable APIC support in the kernel, interrupts from the USB controllers are ignored. The kernel never even notices when I plug in a new device. If I compile the kernel without APIC support, the built-in sound, ethernet, and USB all grab the same IRQ line, and ethernet doesn't work. If I compile the kernel with APIC support, but pass "noapic" to the kernel in grub, all the hardware works, but the kernel log fills up with thousands of "APIC error on CPU0 40(40)" errors!

Right now, I'm letting it pour out errors, because useless kernel logs are better than useless hardware, but I'd like to fix it completely. Any suggestions?

I have a Shuttle SK41 that I am using as a server. The only USB device that I have is an APC UPS that I have not yet configured. I have APIC turned OFF and everything seems to work fine; no errors in dmesg or metalog. The thing that caused me a lot of problems with the Shuttle was ACPI (power management). When I installed Gentoo I added ACPI support to the kernel so I could monitor the CPU temperature. Unfortunately, the built-in sound and ethernet did not work at all with ACPI turned ON.

Keep me posted on what you find out.
