Please boot both broken and working kernel with drm.debug=0xe added to your kernel cmdline and attach the complete dmesg of each to the bug report. If you can do a quick bisect to figure out the offending commit, that would be good, too. And can you please also check whether the latest 3.9-rc kernel is affect? We need to know that since stable rules mandate that regressions in stable kernels can only be fixed once upstream is known to work.
