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

177: 456415 456480 IO-APIC-level eth0

NMI: 0 0
LOC: 39235997 39236069

After a while, I get
irq 185: nobody cared!

Disabling IRQ #185
Then, after some more time, I get
irq 11: nobody cared!
[<c01339e2>] __report_bad_irq+0x22/0x90

[<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?

Solved! After many kernel compile and many kernel paramters,
'acpi=noirq' or 'pci=noacpi' solved the IRQ being disabled.
I'm running Abit VP6 dual-P3 (Via Apollo 133A, VT82C694X, VT82C686B).
