Hello, I'm having a problem with nic on Fedora Core 3. When first installed the USB interface was enabled and eth0 and ohci_hdc were on the same IRQ (#14). After 20 min after boot the nic would stop working and I'd get the following messages: Mar 11 10:02:43 linux1 kernel: irq 14: nobody cared! (screaming interrupt?) Mar 11 10:02:43 linux1 kernel: irq 14: Please try booting with acpi=off and report a bug Mar 11 10:02:43 linux1 kernel: [<02107fa9>] __report_bad_irq+0x3a/0x77 Mar 11 10:02:43 linux1 kernel: [<02108530>] note_interrupt+0x19e/0x1c4 Mar 11 10:02:43 linux1 kernel: [<02108ac7>] do_IRQ+0x24d/0x309 Mar 11 10:02:43 linux1 kernel: [<022a007b>] pci_conf2_read+0xc6/0x1dd Mar 11 10:02:43 linux1 kernel: [<02124f00>] __do_softirq+0x2c/0x79 Mar 11 10:02:43 linux1 kernel: [<021096ee>] do_softirq+0x46/0x4d Mar 11 10:02:43 linux1 kernel: ======================= Mar 11 10:02:43 linux1 kernel: [<02108b77>] do_IRQ+0x2fd/0x309 Mar 11 10:02:43 linux1 kernel: [<0210403b>] default_idle+0x23/0x26 Mar 11 10:02:43 linux1 kernel: [<0210408c>] cpu_idle+0x1f/0x34 Mar 11 10:02:43 linux1 kernel: [<023a86bb>] start_kernel+0x216/0x219 Mar 11 10:02:43 linux1 kernel: handlers: Mar 11 10:02:43 linux1 kernel: [<0228080f>] (usb_hcd_irq+0x0/0x4b) Mar 11 10:02:43 linux1 kernel: [<4290649e>] (tg3_interrupt+0x0/0x1c0 [tg3]) Mar 11 10:02:43 linux1 kernel: Disabling IRQ #14 After disabling USB in the BIOS (this is a server and I don't need it), the OS moved eth0 to IRQ #5 and it is not sharing this IRQ with other devices. There are no other devices sharing any IRQ's in the whole system. The system stays connected to the network for about 6 hours until the nic stops responding again. I now receive this set of messages: Mar 11 14:44:05 linux1 kernel: irq 5: nobody cared! (screaming interrupt?)

I'm at a loss as to what could be causing this. Does anyone have an idea where I should start or how to go about solving this? Thanks, Andrew
