I had upgraded libdrm from 2.4.46 to commit 58d00888 at the same time. The attached dmesg output looks a lot like the bug reported here by José, so I hope I'm not interfering with an unrelated problem. I have been having trouble finding time to investigate, which is why I did not report this myself sooner. I am using a stable 3.10 kernel with DRM cherry picks from 3.11 and upcoming 3.12 -- which is not appropriate for use when reporting bugs. I also did not rebuild the entire X stack when I upgraded, but just libdrm and Mesa. There was a lot of due diligence I needed to perform before filing a bug report here... Anyway, I'm glad to see others reporting this -- now I feel less alone. Not a lot happened in Mesa between 6b5c802c and 2937d704, so if it turns out that my Frankenstein kernel is not to blame, and rebuilding the X stack doesn't help, then I'm going to bisect Mesa. I have "good" and "bad" commits to use, and I'm really interested in seeing whether the one big Radeon change in that interval is the culprit: commit a81beee37e0dd7b75422448420e8e8b0b4b76c1e Author: Alex Deucher <<a href="mailto:alexander.deucher@amd.com">alexander.deucher@amd.com</a>> Date: Fri Sep 6 16:43:34 2013 -0400 radeon/winsys: pad IBs to a multiple of 8 DWs</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
