--- Comment #6 from Maciej Gluszek <info at maciejgluszek.com> --- UPDATE: I removed all additional tested kernel command lines that apply to Radeon besides radeon.dpm=1 for power management. I upgraded Ubuntu library and kernel to 3.16.0-31-generic. Also upgraded Mesa library to 10.3.2 OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV635 OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 10.3.2 OpenGL shading language version string: 1.30 OpenGL context flags: (none) Lockups are still happening. I cannot specify which application is causing this. Lockups happen completly at random times. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
