We don't ask system vendors to fix most bugs we find, because most of them won't talk to us. But we still try to do what we can with the contacts we have available. As far as we can tell there's no additional system wakeups here, so any failure to enter PC6 is because the CPU is in a different configuration. We have a good working relationship with Intel, so asking them if they can help us figure out what that different configuration is seems like a reasonable thing to do? I'm happy to take responsibility for working on it from that point, but I don't believe any of the documentation I'd need to find the starting point is public. -- Matthew Garrett | mjg59@srcf.ucam.org
