the igt_assertion will print the last errno regardless of its relation to the
failed assertion.  That is why it shows -ENOENT here.  My understanding is it
is not related to this issue. 

So, my understanding is that you ran with that parameter and it still fails,
can you please provide the entire log for confirmation?

Thanks!
