--- Comment #8 from Chris Wilson <chris at chris-wilson.co.uk> ---
My working theory for the incompletes as a result of bug 104676 depend on a
reset running concurrently to the tasklet. This bug is the HW reporting the
wrong tail (or rather the tail not being updated before the interrupt is
handled).
