Hi,
There's nouveau crash during boot with 3.9-rc1 on iMac G5 (nVidia GeForce
FX 5200 Ultra). This happens also with current mainline kernel HEAD
(0aefda3e8188ad71168bd32152d41b3d72f04087).
git bisect tells the first bad commit is
1d7c71a3e2f77336df536855b0efd2dc5bdeb41b (drm/nouveau/disp: port vblank
handling to event interface).
The crash is (manually copied from screen):
[...]
Unable to handle kernel paging request for data at address 0x100000000
call trace:
nouveau_event_trigger
nv04_disp_intr
nouveau_mc_intr
nouveau_irq_handler
[...]
I also tried to capture it with netconsole, and got this much:

The cause is event handling linked lists getting corrupted.
I'm not sure how that code is intented to work, but with the below HACK
I can at least boot the iMac without crashing, and get a working display:
