Since kernel 3.4.X (also 3.5-rc) I have been seeing issues with nouveau, machine would lock up almost immediately after grub (after nouveau load) or just simply reboot. The following commit appears to be causing regression on my hardware (found with bisect) - gtx560. Attached is drm.log with portion of kern.log when attempting to insert nouveau (machine was booted with nomodeset and drm.debug=0x04).
4f988d132d2668b4f3b42bfc70daa531115ccca1 is the first bad commit commit 4f988d132d2668b4f3b42bfc70daa531115ccca1 Author: Sascha Hauer s.hauer@pengutronix.de Date: Wed Feb 1 11:38:26 2012 +0100
drm fb helper: remove unused variable crtc_id
crtc_id is set but never used, so remove it from struct drm_fb_helper_crtc.

I have added added crtc_id back to drm fb helper and it seems to solve issues on 3.4.1 so far.
