Any chance this could be related to the irq > synchronisation patches? Could be related, but I'm not sure that's the issue. I don't see any messages at all from the xHCI driver or the USB core about the new host before the "nobody cared" message appears (although it turned out I have CONFIG_USB_XHCI_HCD_DEBUGGING turned off). AFAICT, the driver never gets loaded. But if the xHCI driver failed in its init sequence... I'll check.
