Solution: Move the buffer descriptor to dwords [0:3] or [8:11] of the sampler slot (the image or fmask portion, respectively). Note that on Southern Islands, this condition causes a hang. SI: Move the buffer descriptor to dwords [8:11] of the sampler slot. This will only cause a hang when a buffer is used as sampler2DMS* and vice versa, because dwords[8:11] are unused by other texture types.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
