Andrew, I've hit this multiple times on resume on my laptop, and it's a very apparent bug in that b9d02f1bdd98 commit that it doesn't factor in error pointers. My oops clearly shows it being one too, with ...fff4 being the dereference address.
Can we get this pushed upstream asap if you're fine with this patch?
