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: [ 23.114208] nouveau [ DEVICE][0000:f0:10.0] BOOT0 : 0x034900b1 [ 23.114257] nouveau [ DEVICE][0000:f0:10.0] Chipset: NV34 (NV34) [ 23.114266] nouveau [ DEVICE][0000:f0:10.0] Family : NV30 [ 23.114672] nouveau [ VBIOS][0000:f0:10.0] checking OpenFirmware for image...
