--- Comment #24 from diego.abelenda@gmail.com 2012-04-29 07:45:28 PDT --- Created attachment 60773 --> https://bugs.freedesktop.org/attachment.cgi?id=60773 dmesg with second patch and drm.debug=4

without the second patch doing

xrandr --output VGA-0 --off xrandr --output VGA-0 --auto

logs errors in dmesg

[drm:radeon_dp_link_train_cr] *ERROR* clock recovery reached max voltage [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed

---

with the second patch I have exactly the same error...
