They are the same, it's just that #177701 conflates two issues, a warning (tracked at fdo #973449) and a graphics corruption. The latter appears to be https://bugs.freedesktop.org/show_bug.cgi?id=98402.
The fix has now been pushed to drm-intel-fixes branch of http://cgit.freedesktop.org/drm-intel, which is -rc4 plus half a dozen latest fixes. Please try that and report back.

If drm-intel-fixes doesn't fix the issue for you, please file a *new* bug over at the freedesktop.org bugzilla.
