--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
The error is obvious from the code. It is not platform dependent (other than
the need to have partially setup the guc therefore requiring the guc). It is
not firmware dependent. It is simply a bug in the "huc/guc unwind order
use-after-free(engine) in i915_load_modeset_init error path".

Whilst the error was obvious, fixing the lack of onion unwind was not.
