After removing [numbers] (for WITNESS?), diff started making sense.  
The below is between the first and second suspend/resume cycles in 
dmesg-3.txt, encompassing the others.

Nothing of note that I can see, if that usb hub-to-bus remapping is 
normal.  As you said, 'CPU0: local APIC error 0x40' looks maybe sus.  
Maybe someone who knows might comment on that?

Just checking: you've tried other USB devices apart from uftdi0?

Out of ideas, and my depth, Ian
