Did it ever work? If yes, can you bisect it? Does it work if you power down nvidia card while X is not running? Thanks for your reply Marcin! I wasn't able to boot kernels earlier than 3.6 on this Macbook Pro retina due to various issues, and it occurs on kernels between and including 3.6 and 3.7-rc3. As we see read being called, I've taken the lsof output [1]. Should the DPMS functions be deregistered prior the hardware being placed in D3, or is it more that the functions should check if the card was put into D3 and just return? I'm not sure, but I would bet on adding a check(s). The question is: at which layer (nouveau? drm? fb?)? Another is: are there any other code paths which need to be protected from calling when suspended? (Currently, I don't have answers to these questions and not much time to look into them, sorry.) If no one will figure it out in a few days, please open new bug report - see http://nouveau.freedesktop.org/wiki/Bugs for description how to do this.
