Finally, that was this report concerned : https://bugs.freedesktop.org/show_bug.cgi?id=72921
This patch fixed this issue for me from 3.13 kernel : https://bugs.freedesktop.org/attachment.cgi?id=101191 Until now, I had tested only with 3.14.12 kernel from upstream with great success (no reboot and better performance). I'll test with debian 3.14.0 from bpo as soon as possible. This issue affects APUs from AMD.
