dmesg with 3.11.5+patch
(In reply to Alex Deucher from comment #6)
> Do you have dpm enabled (radeon.dpm=1 on the kernel command line in grub,
> etc.)?
Nope, I have not touched Ubuntu 12.04 boot options:
$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.11.5+ root=UUID=9f5a9635-088b-43a8-9444-a3c642a81256
ro quiet splash vt.handoff=7
> dpm is disabled by default so unless you have enabled it, none of
> that new code added in that patch gets executed. You might be missing the
> smc ucode file for which would explain why your patch fixes the issue.
> Please attach your dmesg output.
