    SubjectPROBLEM: nouveau & ttm module crashes
    Hello,

    I have had some problems with nouveau on my box. Loading the module
    crashes Linux 3.2.1 (modprobe hangs with kernel trace). The following two
    code fragments are relevant and should be changed:

    1) drivers/gpu/drm/ttm/ttm_bo.c - line 1529
    you should comment BUG_ON; this validation will be done two lines later
    in drm_mm_takedown more gracefully. On my box this line is triggered
    and results in a hang of modprobe.

    2) drivers/gpu/drm/nouveau/nouveau_hw.c - line 1024
    dev!=NULL but dev->vblank_enabled == NULL (is not catched and results in
    Null pointer reference)

    With both changes it is possible to load nouveau without kernel crashes on
    my box.


    Regards,
    Lars
