This would be a kernel issue (not X.org/userspace). You would be much better off posting to something like dri-devel list or somewhere else that actually gets view from open-source radeon devs.

I might try to tun a LiveUSB of 14.04 there to see if it boots correctly. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1321889 Title: Radeon 4550 can't boot without radeon.audio=0 since kernel 3.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1321889/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
