Could be USB, more likely ACPI. I've seen this one happen nearly every boot since then including bootups that are otherwise OK (no oopses), so it's probably worth more looking into rather than being written off as a 'once off': uhci_hcd 0000:00:1d.3: Unlink after no-IRQ? Controller is probably using the wrong IRQ.
