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.
