What symptoms? What exactly is going wrong? Thinking about it the sequence probably won't get reseted when we encounter a unrecoverable GPU lockup. And even when the partial GPU reset fails it might be a good idea to reset the fence sequence like this.... Ok, you're right there is something wrong. Going to write a patch for this...
