Before that we could try to narrow down things by disabling each test step. Could you try applying the attached disable patches and see with which ones the gpu-blit test stops hanging (if at all :P)? First with patch 1, then patch 1+2, then 1+2+3 etc. Thanks.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
