Gen3 doesn't have gpu reset implemented, hence the error message (yeah, it's not too informative). But since

    drm/i915: fixup hangman rebase goof-up

(on -queued) the kernel should properly ignore this error if the gpu hang is simulated with ZZ_hangman (but only if the reset fails because it's not implemented, not when it fails for other reasons).
