--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
So that is wait_for_atomic() complaining about the _WAIT_FOR_ATOMIC_CHECK()
failing, i..e that we used wait_for_atomic() from an ordinary process context.

So normally the tasklet would be called from softirq context but in this case,
it's a call by intel_engine_is_idle() doing the direct check for fast idling.
Ok, seems easy to fix...
