Kernel bisect

Updating to a kernel > 3.8, the monitor connected via display port shows heavy
colour distortions (see attached image). 
I bisect the kernel and it came down to patch 

5cc027f6b1ec651c18a4322ed3e30c6e9cf01e96
(drm/nv50-/disp: move DP link training to core and train from supervisor)

This makes sens, since this patch deals with display port functions. 

The problem appears during boot and hence I guess it is part of the DRM resp.
KMS part.

Attached are dmesg outputs for a working and a non-working kernel.
An image which shows the kind of distortions and the kernel bisect log.

Relevant system infos:

01:00.0 VGA compatible controller: NVIDIA Corporation GF108GL [Quadro 600] (rev
a1)
