           Summary: r600g regression : vertex buffer alignement
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: pelloux@gmail.com


I have a simple app using vbo to render models.
The VBO layout is : position (3 float), normal (3 float), color (3 char)

This app was running perfectly until I updated libdrm/mesa to git version.
Now the app still does not have any GL error set (checked with glGetError()),
but its rendering is completely wrong.

git-bisect pointed me to this commit :
  0ed5bf668db24fb56b5b359399099c89531e2a0a
  "r600g: Request DWORD aligned vertex buffers."


OS : Debian unstable (amd64)
Radeon HD 4850
