I applied this patch against the current linux kernel of the Arch
Linux distro (3.12.9-2) including all there magic during package
build, just to see it works downstream. (had to recreate the patch but
the actual changes were not changed).
After applying this patch the bug was gone.
On
Commit 0a0afd282f ("drm/nv50-/disp: move DP link training to core and
train from supervisor") added code that uses the wrong register for
computing the display bpp, used for bandwidth calculation. Adjust to use
the same register as used by exec_clkcmp and nv50_disp_intr_unk20_2_dp.
