dmesg | grep nouvea, with 3.6.10-4

Hello, I am running fedora 18. I have 3 monitors hooked up to a geforce gtx 660
ti, 2 via the DVI connectors, and 1 via the displayport connector. With Kernel
3.6.10-4, everything works fine. Upon upgrading to 3.7.2-201, the displayport
connected monitor stops working and says unsupported display mode, optimal
resolution is xx (the monitor is set to that resolution and hz).

The unsupported display mode is displayed even in runlevel 3. I have changed
the monitor connectors around and whichever is connected via displayport stops
working. 

If I boot back to 3.6.10-4, everything works fine.

If I do a dmesg |grep nouveau , on 3.7.2-201, I see: 
  2.012167] nouveau E[     DRM] failed to create kernel channel, -22            

This message does not get displayed with 3.6.10-4.
