Ignore my previous message, this is what happens when you try and answer 
e-mails with a head full of pain killers.

IRQ 16:

16:     200001          0          0          0  IR-IO-APIC-fasteoi 
ehci_hcd:usb1

Looks like ehci_hcd (USB1) is being disabled. We should check that out. 
So file a bug, it needs investigating.
