When enabling randr12 on my nv34 the image on the screen is unstable. This is with a single CRT output.

Comment 2 Maarten Maathuis 2008-03-06 12:00:25 UTC 
Could you run both randr12 and non-randr12 with NOUVEAU_MODESET_TRACE (nv_local.h) enabled?

non-randr12 log is at: http://peter.whoei.org/nouveau/Xorg.0.log-modeset_trace and randr12 log is at: http://peter.whoei.org/nouveau/Xorg.0.log-modeset_trace-randr12

Untested patch to use old PLL calculator

Try this to see if the chosen PLL values are the problem (patch isn't tested, but should work :) )
