--- Comment #13 from Benjamin Bellec b.bellec@gmail.com --- Alex, I saw you disabled RV770 mclk switching to kernel 3.13.3 and 3.12.11. Thank you, it's now much more comfortable (tested with Fedora 19 kernel 3.12.11).
Anyway, do you plan to add your patch to kernel 3.10 too? It's a long-term release and will be used by RHEL7.
