In gentoo-dev-sources, when I have my NIC enabled, after it runs for a while, the following appear in dmesg: irq 10: nobody cared! [<c010634a>] __report_bad_irq+0x2a/0x90 [<c010643c>] note_interrupt+0x6c/0xa0 [<c0106711>] do_IRQ+0x121/0x130 [<c01049f4>] common_interrupt+0x18/0x20 handlers: [<c02e3f60>] (usb_hcd_irq+0x0/0x70) [<c02e3f60>] (usb_hcd_irq+0x0/0x70) Disabling IRQ #10 I notice that this only happen when I have NIC enabled (thru dhcp). If I don't use the NIC, this won't happen. Then, a check at /proc/interrupts show: CPU0 0: 29357037 IO-APIC-edge timer 1: 5502 IO-APIC-edge i8042 5: 1205448 IO-APIC-level VIA8233 8: 2 IO-APIC-edge rtc 9: 0 IO-APIC-level acpi 10: 100000 IO-APIC-level uhci_hcd, uhci_hcd 12: 290275 IO-APIC-edge i8042 14: 14854 IO-APIC-edge ide0 15: 21748 IO-APIC-edge ide1 16: 2262508 IO-APIC-level nvidia 19: 1019615 IO-APIC-level eth0 NMI: 0 LOC: 29357059 ERR: 0 MIS: 0 Notice in IRQ 10, the "100000" is fixed in this cased. When it increment to 100000, the error occur. If NIC is not enabled, it will remain at 2 and will not increment. I notice that in my system configuration screen before the OS boot, NIC and USB share the same IRQ, that's IRQ 10. If I disable APM and ACPI together in the BIOS and kernel, the uhci is mapped to IRQ 26, and the error still occur. But with ACPI enabled in BIOS and kernel, the NIC is mapped to IRQ 19, the exact same as seen in Windows XP. uhci remains at IRQ 10 in both cases.

Can you see if you get this error with development-sources, please?
i tried development-sources 2.6.8-rc2 and the problem went away. :) i will use it for a while and see if there is any problem but so far so good
I'm closing this as FIXED as per comment #2. If you still have this issue with newer kernels or gentoo-dev-sources-2.6.8 then please reopen this bug. Thanks!
I used to have the same problem with various flavours of the 2.6 kernel. I am currently using the 2.6.8-gentoo-r3 kernel and it happened on me too. I googled and I found that this could be caused by spurious interrupts caused by the IO-APIC code. Can you try booting your old kernels with "nolapic" and see if it solves the problem. It worked on mine.
