Hi Mao, Thanks for that.
You are right, this should be split into two kernel issues. I have opened: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1698700 - "pci:" prefix in bus ID https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1698706 - Quirk for vga card and bridge I have subscribed you to these bugs. They include some updates to the upstreaming process and I will keep them updated. If it's alright with you I will close this bug as we've established it's not a bug in X.
