--- Comment #13 from Simon Farnsworth <[email protected]> 2011-11-28 06:44:35 PST --- Looks like the pageflip hang is a red herring; I changed the existing DRM_DEBUG in evergreen_page_flip to DRM_ERROR, and added a new one just before the loop to tell me what crtc_base should be once the flip has completed. I get: [ 79.049935] [drm:evergreen_page_flip] *ERROR* Updating to 0x24d0000 [ 79.052905] [drm:evergreen_page_flip] *ERROR* Update pending now high. Unlocking vupdate_lock.
