Which kernel version? Did you try 3.12? Please attach dmesg from early boot with drm.debug=0xe module parameter.
(In reply to Jani Nikula from comment #1) > Which kernel version? Did you try 3.12? Please attach dmesg from early boot > with drm.debug=0xe module parameter. It was fixed in 3.11.4 and later. Forgot to close this. Thanks.
