Hi Nikolaus,

please try the patch below:

diff --git a/drivers/gpu/drm/omapdrm/omap_fbdev.c b/drivers/gpu/drm/omapdrm/omap_fbdev.c index 561c4812545b..2c8abf07e617 100644 --- a/drivers/gpu/drm/omapdrm/omap_fbdev.c +++ b/drivers/gpu/drm/omapdrm/omap_fbdev.c @@ -232,6 +232,8 @@ void omap_fbdev_init(struct drm_device *dev) if (!priv->num_pipes) return;

• dma_coerce_mask_and_coherent(dev->dev, DMA_BIT_MASK(32));
• fbdev = kzalloc(sizeof(*fbdev), GFP_KERNEL); if (!fbdev) goto fail;

Yes, it fixes the issue!

BR and thanks, Nikolaus
