Can you boot your kernel with "log_buf_len=8M drm.debug=0x14 nouveau.debug=disp=trace,i2c=trace,bios=trace" and post an updated log?

(In reply to xen from comment #3) > Created attachment 130842 [details] > photo taken from primary output during boot Ah, thank you. I know what's going on here, it relates to some as of yet unimplemented display architecture changes that GM20x requires. I shall fix it, but it might take me a little while to figure out how exactly to go about it.

If you build the kernel module from my tree, I believe your issues will be resolved now.  https://github.com/skeggsb/nouveau/commits/master
