It turns out that the problem is one of the RADEON_READs in radeon_get_vblank_counter(). For some reason, the function is being called after dev_priv->mmio is set to NULL, and when the pointer is dereferenced, hell breaks loose. So what's the proper fix for this? Another assertion with a DRM_ERROR like the other two in that function, and then a quest to find why radeon_get_vblank_counter() is called so late? - Steven ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
