Given attempts I can eventually get to a somewhat functional VT. dmesg output attached.

Biederman <ebied...@xmission.com> Date: Mon Dec 17 17:19:36 2012 -0800 efi: Fix the build with user namespaces enabled. This doesn't apply to your situation on many levels... this is a build fix... to efi vars... I bet if you checkout to 992956189de58cae9f2be40585bc25105cd7c5ad^ then you will still have a bad kernel. You should probably redo the bisect, but look at the bisect log (git bisect log) and keep all your "bad" commits, since they are likely indeed bad. But you may have been a bit too eager in calling out the "good" kernels. (See git help bisect for how to start with a bunch of bad commits.) While you're at it, you may want to re-test whether 3.7 really is good.

Upon resuming, the X session was frozen with the cursor being updated occassionally. After several attempts I was able to get to a VT. Shortly thereafter the X server died, causing lightdm to respawn a greeter which functioned correctly, presumably because it doesn't require acceleration. I could log in again, also the X session would freeze before getting to a functional desktop (presumably upon compiz starting). Again, with a few tries I could get back to a VT, at which point lightdm would start a greeter. With every freeze a "failed to idle channel 0xcccc0000" message would be dumped to dmesg.

For example, in the removed code, nv50_display_fini did stuff. In the current code, it's basically empty (well, some small bits in nouveau_display_fini). It looks like the old code (a) blanked each crtc (b) sent out a EVO_UPDATE command (c) waited for each crtc to hit a vblank (d) did something with the cursor (cleared it?) (e) waited for some sort of DPMS thing It could well be that this now happens elsewhere, but I just wanted to put that thought down on "paper".
