Disabling IRQ #xx, because nobody cared!

[William Park]

I'm runing 2.6.10 SMP.  I usually use APM, but I decided to try ACPI.
On my machine, USB (integrated) and Audio (PCI card) shares IRQ:

	       CPU0       CPU1       
      0:   19281733   19952671    IO-APIC-edge  timer
      1:      51751      53105    IO-APIC-edge  i8042
      4:    1613559    1503569    IO-APIC-edge  serial
      7:          0          0    IO-APIC-edge  parport0
      8:          2          0    IO-APIC-edge  rtc
      9:          0          0   IO-APIC-level  acpi
     11:     149496     150504   IO-APIC-level  uhci_hcd, uhci_hcd
     12:      54518      50376    IO-APIC-edge  i8042
     14:      63398      63535    IO-APIC-edge  ide0
     15:          1          1    IO-APIC-edge  ide1
    169:      11440      11565   IO-APIC-level  ide2
    177:     456415     456480   IO-APIC-level  eth0
    185:      50307      49693   IO-APIC-level  Ensoniq AudioPCI
    NMI:          0          0 
    LOC:   39235997   39236069 
    ERR:          1
    MIS:          0

After a while, I get

    irq 185: nobody cared!
     [<c01339e2>] __report_bad_irq+0x22/0x90
     [<c0133ad8>] note_interrupt+0x58/0x90
     [<c0133578>] __do_IRQ+0x128/0x130
     [<c0104eba>] do_IRQ+0x1a/0x30
     [<c010370a>] common_interrupt+0x1a/0x20
     [<c0100690>] default_idle+0x0/0x40
     [<c01006ba>] default_idle+0x2a/0x40
     [<c0100760>] cpu_idle+0x40/0x70
    handlers:
    [<e086e000>] (snd_audiopci_interrupt+0x0/0xc0 [snd_ens1371])
    Disabling IRQ #185

Then, after some more time, I get

    irq 11: nobody cared!
     [<c01339e2>] __report_bad_irq+0x22/0x90
     [<c0133ad8>] note_interrupt+0x58/0x90
     [<c0133578>] __do_IRQ+0x128/0x130
     [<c0104eba>] do_IRQ+0x1a/0x30
     [<c010370a>] common_interrupt+0x1a/0x20
     [<c0100690>] default_idle+0x0/0x40
     [<c01006ba>] default_idle+0x2a/0x40
     [<c0100760>] cpu_idle+0x40/0x70
     [<c03728c7>] start_kernel+0x147/0x170
    handlers:
    [<c0227ef0>] (usb_hcd_irq+0x0/0x60)
    [<c0227ef0>] (usb_hcd_irq+0x0/0x60)

At which point, USB is dead.

Do you know if 'acpi' is responsible for this?
