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
