It doesn't look like the patch from comment 2 landed in mainline or linux-next as of yet. Do you plan on submitting your patch upstream? We could integrate either patch into the Ubuntu kernel, but we prefer to use the one that is in the upstream kernel. I built a test kernel with the patch from

This has something to do with using DisplayPort monitors (through the two DisplayPort connectors on the laptop dock). When the laptop is undocked and a single external monitor connected to the HDMI port on the laptop itself, nouveau works fine. Dock the laptop and suddenly it can't boot any more.
