I've seen this problem under stress, not normally during boot. Time 
permitting I will have a look into this next week.

Probably a race condition somewhere.

Could you tell me whether the panic appears after a lengthy wait or is 
it directly related to a an event like plugging in a device or starting 
to talk to it (usbd, ugen, etc.)

Cheers,

Nick
