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.
