--- Comment #1 from Lionel Landwerlin <lionel.g.landwerlin at linux.intel.com> ---
Chris asked me to look into this, just in case I had any idea.
I was first confused by the internal documentation (containing a GEN9 change
making look like GEN11), turns out there is nothing wrong there.

I couldn't reproduce the issue on my side, I did get an unclaimed register
access though. This unclaimed access is fixed by :
