It's not.

The actual bug was panel self refresh. It's still broken, and doesn't
work. So enabling it by default was a big mistake (commit
b6d547791fd3: "drm/i915: Enable PSR by default.")

I've reverted that commit, you guys can try again with PSR for the
next kernel release if somebody figures out how to get the damn thing
*out* of panel self-refresh (because that's what I'm assuming is going
on: the graphics may still work fine, but nothing updates on the panel
any more).
