that looks fine to me.
The runtime_resume path points to intel_dmc_load_program(). The
preempt-disable section there was introduced by commit
   dff457d74e7ea ("drm/i915: Speed up DMC firmware loading")

and the other thing seems to be intel_irq_reset() not sure where but it
is the runtime_suspend path.

So disabling runtime-suspend should help.
