Sure you don't mean ehci_hcd? Acoording to your /proc/interrupts listing, it is the driver using IRQ 23. > and modprobeing it brings it back for a few more minutes but > the message pops back up.

Maybe the kernel thinks it is using some other IRQ or maybe the kernel doesn't know of the device's existence at all. You could compare /proc/interrupts with earlier kernel versions to see if anything has changed. Sometimes problems in the ACPI drivers can cause this behavior. You can try booting with acpi=noirq.
