2.6.7-mm3 USB ehci IRQ problem

With 2.6.7-mm3 I am missing my USB 2.0 memory stick. It doesn't show up in the usb device listing. But when I unplug it I get:

irq 23: nobody cared!

 [<c0108106>] __report_bad_irq+0x2a/0x8b
 [<c01081f0>] note_interrupt+0x6f/0x9f
 [<c0108473>] do_IRQ+0x10c/0x10e
 [<c0106850>] common_interrupt+0x18/0x20

handlers:
[<f9d0f65c>] (snd_emu10k1_interrupt+0x0/0x3c4 [snd_emu10k1]) Disabling IRQ #23

The soundcard is still usable but there are no new interrupts.

When I try to reload the ehci module I get:

ACPI: PCI interrupt 0000:00:1d.7[D] -> GSI 23 (level, low) -> IRQ 23 ehci_hcd 0000:00:1d.7: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller
ehci_hcd 0000:00:1d.7: BIOS handoff failed (104, 1010001) ehci_hcd 0000:00:1d.7: can't reset
ehci_hcd 0000:00:1d.7: init 0000:00:1d.7 fail, -95
ehci_hcd: probe of 0000:00:1d.7 failed with error -95

IRQ23 is normally shared between emu10k1 and the ehci controller without problems.

Could you please do a `patch -p1 -R' of ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.7/2.6.7-mm3/broken-out/bk-acpi.patch ?

Unfortunately no improvement. Unplugging the non-working USB stick still gives:

ACPI: PCI interrupt 0000:02:0b.0[A] -> GSI 23 (level, low) -> IRQ 23 irq 23: nobody cared!
