One patch submitted. And I can't figure out why, but the timer that is supposed to be deleted by drm_vblank_cleanup() isn't getting destroyed. And once the timer fires, the device is already invalidated, and it oopses in radeon_get_vblank_counter(). The obvious temporary solution is a check whether dev->mmio is a valid pointer, and if not, return -EINVAL. But obviously, fixing the timer is more ideal. - Steven. ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
