Same freeze on the exit > of Dolphin. Here's the new dmesg log. Hope I did it right. Yeah, thanks! That's exactly what I needed. And my initial suspicion was right, for some reason we try to free the SG table twice: [ 141.833287] [drm:radeon_ttm_backend_unbind [radeon]] *ERROR* ttm->sg = ffff880222930e00, ttm->sg->sgl = ffff8802238bd200 ... [ 141.898159] [drm:radeon_ttm_backend_unbind [radeon]] *ERROR* ttm->sg = ffff880222930e00, ttm->sg->sgl = (null) Which then obviously causes problems. For a quick fix we could try to double check if we haven't already freed the table, but I think the underlying problem is that we try to free the BO twice as well. @Michel any ideas?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
