linux 3.9-rc1: nouveau crash on PPC

Sat Mar 9 10:44:31 PST 2013

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:
