           Summary: nouveau KMS: null pointer dereference if native mode is
                    not found
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: anssi-4qZELD6Fgxhg9hUCZPvPmw@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


When native mode is not found by KMS, at least with NV40, there is a null
pointer dereference of native_mode in nv_output_mode_fixup() when starting X.

Kernel log attached.

(In this case native mode is not found because of "Output script table version
0x11 unknown"; I'll open a separate bug for that with proper info if none is
already open)
