Yes, it is unknown why we get a spurious interrupt. Might it be an ACPI issue?
Could ACPI touch EHCI when going into C states?
The patch does acknowledge the interrupt although it was not requested. We are
getting some interrupts after that. If it is a finite number I think we can
live with that as an oddity of that hardware. If not, I'll dig deeper. That
still needs to be determined.
