Running 2.6.9-rc1-mm4 with the above patch.
I'm a bit unsure of the timing, but at some point I got this either before or during the transfer I set up to get some Tx activity, a repeated wget of a 35M file.
irq 10: nobody cared! [__report_bad_irq+36/144] __report_bad_irq+0x24/0x90 [note_interrupt+146/352] note_interrupt+0x92/0x160 [do_IRQ+354/416] do_IRQ+0x162/0x1a0 [common_interrupt+24/32] common_interrupt+0x18/0x20 [default_idle+0/64] default_idle+0x0/0x40 [default_idle+44/64] default_idle+0x2c/0x40 [cpu_idle+52/80] cpu_idle+0x34/0x50 [start_kernel+347/384] start_kernel+0x15b/0x180 [unknown_bootoption+0/368] unknown_bootoption+0x0/0x170 handlers: [usb_hcd_irq+0/112] (usb_hcd_irq+0x0/0x70) [usb_hcd_irq+0/112] (usb_hcd_irq+0x0/0x70) Disabling IRQ #10
I killed the transfer and started X, getting this immediately:
irq 16: nobody cared! [__report_bad_irq+36/144] __report_bad_irq+0x24/0x90 [note_interrupt+146/352] note_interrupt+0x92/0x160 [do_IRQ+354/416] do_IRQ+0x162/0x1a0 [common_interrupt+24/32] common_interrupt+0x18/0x20 [default_idle+0/64] default_idle+0x0/0x40 [default_idle+44/64] default_idle+0x2c/0x40 [cpu_idle+52/80] cpu_idle+0x34/0x50 handlers: [rtl8169_interrupt+0/464] (rtl8169_interrupt+0x0/0x1d0) Disabling IRQ #16
This also happened during the originally-reported incident, which I forgot to mention. Both times, downing and then upping the interface resulted in what seemed like a solid hang, although possibly it was just X.
I rebooted and started X again, and again got the above. If I boot with acpi=noirq, I don't get that message upon starting X. Here's /proc/interrupts before and after starting X, without passing acpi=noirq:
CPU0 CPU1 0: 18810 52561 IO-APIC-edge timer 1: 142 8 IO-APIC-edge i8042 5: 0 0 IO-APIC-level acpi 8: 2 2 IO-APIC-edge rtc 10: 3651 3367 IO-APIC-level uhci_hcd, uhci_hcd 11: 0 0 IO-APIC-level VIA686A 14: 2 13 IO-APIC-edge ide0 16: 10 8 IO-APIC-level eth2 17: 12 7 IO-APIC-level eth1 19: 2989 2564 IO-APIC-level aic7xxx NMI: 0 0 LOC: 71037 71036 ERR: 0 MIS: 0

I don't know if this is significant, but with acpi=noirq, /proc/interrupts looks like this:
CPU0 CPU1 0: 196902 25653 IO-APIC-edge timer 1: 64 1189 IO-APIC-edge i8042 2: 0 0 XT-PIC cascade 5: 0 0 IO-APIC-edge acpi 8: 2 2 IO-APIC-edge rtc 9: 93 4 IO-APIC-level eth1 10: 2438 4609 IO-APIC-level aic7xxx, uhci_hcd, uhci_hcd 11: 10 15775 IO-APIC-level eth2, radeon@PCI:1:0:0 12: 0 0 IO-APIC-level VIA686A 14: 10 5 IO-APIC-edge ide0 NMI: 0 0 LOC: 222226 222225 ERR: 0 MIS: 0
eth2 being the 8169.
Unfortunately after tonight I won't have access to this machine until Friday evening. I'll grab the netdev patchset and try those next. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
