To address this bug, we're going to release 3.16.0-70.90~14.04.1 comprised of just this fix. That kernel will become available in the -proposed archive in the next day or two (an announcement will be posted here).
In the meantime, a preview build of that kernel is available here (this replaces jsalisbury's test kernel from comment #4): http://kernel.ubuntu.com/~kamal/lp1566726.0/ Affected users, please confirm that preview kernel resolves the problem (likely only the linux-image-3.16.0-70...deb needs to be installed). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1566726 Title: System freeze after update to 3.16.0-69-generic [NULL pointer reference in radeon_fence_ref] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
