Bug 102372

Please attach your full dmesg output from when the driver loaded and your xorg log.

The driver is built in, I noticed Dave spotted the same (or similar issue) 

Harry Wentland said he sent a patch fixing the issue but I don't think it's included in your tree yet and I'm not sure which is the right patch

Thought I'd revert and retest with all the latest code

KMS does work but X doesn't start

Looks like X starts now with the drm-next-4.16-wip branch

There's still an error in the logs:

I'll check drm-next and Linus's branches when I get home so we can hopefully revert the kabini disablement on DC

What physical display connectors are actually on the board?

I've just checked https://www.computeruniverse.net/en/products/90526096/acer-aspire-xc-105.asp

It has HDMI and a VGA connector, I've only ever used the HDMI connector

Whilst I still get the following message:

[    0.583506] [drm:construct] *ERROR* construct: Invalid Connector ObjectID from Adapter Service for connector index:1! type 0 expected 3

DC does now work on Kabini, so can the following revert be applied

Revert of the Kabini DC disablement

I can send this to the list, though happy for you just to apply it

Poke: this should be reverted, as mentioned in IRC enabling DC has unfortunately broken the displays on this TONGA GPU as well. GPU info:

[AMD/ATI] Tonga PRO [Radeon R9 285/380] [1002:6939] (rev f1)

Tonga is a different generation of display hardware so is unrelated to this.
