I have tested the laptop with linux-3.10-rc5 with this patch series applied: https://lkml.org/lkml/2013/6/13/349 The testcase is: boot with the dock station attached, let Xorg start (it will use both Intell and Radeon cards), switch to a virtual console, press the Undock button. Yes I know that GPU hotplug is not yet supported in Xorg, but attempting it should not lead to messages like "kernel BUG at drivers/gpu/drm/ttm/ttm_bo.c:1591!" The part of the dmesg after the undocking attempt, captured over netconsole, is attached to this bug. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
