lspci -vv

The fan on my GeForce GTX 275 turns on to full speed after resuming from suspend.
This started with Linux 4.3-rc1, and does not happen in 4.2-rc8.
I am running Arch Linux and compiling my kernel from git, with mesa 10.6.7 and xf86-video-nouveau 1.0.11.
I have attached lspci output for my card.
I did a git bisect and came up with this:
first bad commit: [2aa5eac5163fedf09f2d61992cb5ea4d75bec9db] drm/nouveau/i2c: transition pad/ports away from being based on nvkm_object

Wow that's a monster commit. Which also happens to change the semantics of a *whole lot* of stuff. Unfortunately this will have to wait for Ben to take a look. In the meanwhile, would you mind posting a dmesg when the kernel is booted with nouveau.debug=debug from both right before and at this commit? Should hopefully show what's going wrong.

I just pushed a fix[1] to my tree, and will get it into 4.3 before it's released.
