--- Comment #5 from Alex Deucher <alexdeucher at gmail.com> --- Created attachment 147331 --> https://bugzilla.kernel.org/attachment.cgi?id=147331&action=edit possible fix As you can see from your log, the vblank time for the mode you've selected is right at the mclk switching limit: [ 5.943137] vblank_time 450, switch_limit 450 so I guess in your case, there are times when it doesn't quite complete in time. A minor adjustment to the comparison should fix it. -- You are receiving this mail because: You are watching the assignee of the bug.
