I don't see anything wrong. There is small difference in timing and
then the RT version does not do a thing while !RT keeps reseting…
Could you try non-RT with the
	threadirqs

option?

Yes, (sorry for not including that earlier D:) that fails the same way
as the realtime kernel:

Could be specific to the chip or the ohci driver. Either way, the problem
are the threaded interrupts.

David, could you please try a v5.10 kernel with threadirqs? I've been
just told that it works there on a ppc64 box.
