--- Comment #27 from Imre Deak <imre.deak at intel.com> ---
I believe that S3 failing in itself (so not the hotplug issue originally
reported) is not a BIOS issue. I could reproduce it on my machine with a recent
BIOS:
APLKRVPA.X64.0130.B11.1603210634

With a few fixes S3 works now for me and those fixes could be also relevant
here.
So Humberto, besides trying to upgrade the BIOS as Yann suggested could you
also try the following branch:
