Public bug reported: Hi,
after upgrade to utopic, regular freezes for some seconds to some minutes appeared. Using custom kernel compiled from provided source of 3.16.0-11.16 with CONFIG_DMA_CMA=n solves the problem. Linux freezes with up-to-date linux-image from repository (version 3.16.0-11.16). It doesn't matter, whether I use radeon or vesa driver. Discussion about the bug in either X or kernel happened on http://lists.freedesktop.org/archives/dri-devel/2014-August/065842.html ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "lspci" https://bugs.launchpad.net/bugs/1363384/+attachment/4190754/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1363384 Title: CONFIG_DMA_CMA causes performance problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1363384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
