This looks to be a spin_lock_irq() in the reset path.

This is probably the result of using execlists_set_active()
outside of the tasklet.
Honestly, not as scary as I expected.
The question of whether allowing preempt-timeout for bdw was a
deliberate error or not remains open. Otoh, it does give the same
guaranteed QoS to the preempter, but at the same time we don't give much
opportunity for the active context to vacate.
