32167016076f714f0e35e287fbead7de0f1fb179 seems to be the first bad commit bug seems to affect only the RS880 series and older Christian König proposed a patch to limit the reference divider to fix this and it seems to work. Alex Deucher has committed it upstream http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=72edd83cc9e5819ed1ee771519143d7594e059f0 Hope it will land soon in Ubuntu. ** Bug watch added: Linux Kernel Bug Tracker #83461 http://bugzilla.kernel.org/show_bug.cgi?id=83461 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1479136 Title: [ubuntu 14.04.2] Artefacts in radeon driver on kernel 3.16 and upwards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1479136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
