[Nouveau] [Bug 71824] [NVE6] NULL deref on boot when there is nothing in DCB on 3.13-rc

I think this will lead to chan->vblank.nr_event = pdisp->vblank->index_nr; failing in nv50_software_context_ctor, called from nouveau_accel_init since pdisp->vblank == NULL. I suspect that ->index_nr is at offset 0x130 which explains the CR2 that you see. As a temporary workaround, booting with nouveau.noaccel=1 will avoid the crash (and also remove your ability to use the card). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
