I have an ASUS P6X58D-Premium mobo with a GeForce 9400GT PCIe video card. With kernel 3.12-rc1, I get scrambled video on boot. Kernel 3.11 works fine.
Bisecting this, I found 7c510133d93dd6f15ca040733ba7b2891ed61fd1 "drm: mark context support as a legacy subsystem" is the guilty commit. If I revert that commit, the video works fine.
Is there any more info I can provide?
Full dmesg, and what driver you are using.
Driver is nouveau.
The dmesg from a good boot with the commit reverted is attached.
For the bad boot, the dmesg log is filled with messages like this:

I will try next with the patch series you sent to Linus yesterday, to see if that happens to fix this.
Nope, with your patch series from yesterday the problem still exists.
Just to double-check: Does the revert still work, even on latest upstream git + Dave's pull request? -Daniel
