Hi,
I have a AMD64 x2 4800+ system built on an asus A8V-deluxe

After running flawlessly with a kernel 2.6.14.3 for 6 months and the FC4 packages,

I saw this appear in dmesg :


irq 10: nobody cared (try booting with the "irqpoll" option)

Call Trace: <IRQ> <ffffffff8015dcd5>{__report_bad_irq+53} <ffffffff8015df4a>{note_interrupt+538}
<ffffffff8030e4ce>{usb_hcd_irq+30} <ffffffff8015d6df>{__do_IRQ+207}
<ffffffff801109af>{do_IRQ+47} <ffffffff8010e276>{ret_from_intr+0}
<EOI> <ffffffff802480ed>{acpi_processor_idle+303} <ffffffff8010c6af>{cpu_idle+79}
<ffffffff805d881a>{start_kernel+474} <ffffffff805d8223>{_sinittext+547}

handlers:
[<ffffffff80294f30>] (skge_intr+0x0/0x840)
[<ffffffff880065a0>] (ata_interrupt+0x0/0x180 [libata])
[<ffffffff8030e4b0>] (usb_hcd_irq+0x0/0x50)
[<ffffffff8030e4b0>] (usb_hcd_irq+0x0/0x50)
Disabling IRQ #10

The handlers seem to indicate that 4 peripherals share IRQ10, among which an ata controller (must be the SATA controler as my IDE hard drives still work, I have no SATA drives)

the error trace above seems to point out USB as the faulty component?

does that mean that my usb controller is physically dead?

Thank you for any help in decyphering these rather cryptic messages.

By chance have you recently flashed your cmos setup or upgraded your bios?

No, not for the past 6 months!

I had to try different BIOS versions for the x86_64 SMP kernel to work with the whole 4 Gigs of ram, but the hardware and kernel configuration has been unchanged for 6 month...

So this looks more and more like a hardware fault I'm affraid... The problem is that I can't distinguish which of the VIA SATA, USB or integrated NIC is dead because they are all disabled...

Try adding "acpi=noirq" to grub.
