--- Comment #24 from Pekka Paalanen <ppaalanen at gmail.com> ---
Tried the complete kernel from nouveau/drm-nouveau-next
(v3.13-rc8-665-g1139ffb) which contains the commit

commit f87cd8b695d372087685976460fac1ec6ba2fca9

    drm/nouveau/devinit: lock/unlock crtc regs for all devices, not just
pre-nv50

    Also make nv_lockvgac work for nv50+ devices. This should fix
    IO_CONDITION and related VBIOS opcodes that read/write the crtc regs.

which apparently is supposed to fix the issue.

This kernel works, and the issue is fixed.

Thank you!
