    initial v1  
    1 Looking through the last attached syslog I found this line:
     1Looking through the last attached syslog I found a lot of differences with the DRM log.
     2Haiku:
    23        KERN: radeon_hd: display_crtc_fb_set: Framebuffer at: 0x0
    3 Is it normal to have framebuffer at 0x0? Could you attach a syslog from any proper radeon_hd boot for me to compare?
     4        KERN: radeon_hd: display_crtc_fb_set: Set SurfaceAddress High: 0x0
     5        KERN: radeon_hd: display_crtc_fb_set: fb pitch: 1376
     6Linux:
     7        [drm] fb mappable at 0xD0142000
     8        [drm] vram apper at 0xD0000000
     9        [drm] size 4325376
     10        [drm] pitch is 5632
     11
     12Clearly, the framebuffer address is invalid (0x0), and the pitch is totally wrong. Firstly, because it doesn't take into account 4 bytes per pixel. Secondly, because of a smaller alignment (DRM's 5632 = 4 * 1408).

     14kallisti5, could you comment on that?
