I've observed that "FIFO is overflown by GatherPipe" is not real overflow.

Browse Source 
Really that happens because the fifo.CPReadWriteDistance is negative.
Example: CPReadWriteDistance: -864 CPEnd: 10092672 fifo.CPBase: 9568416
In SMG this is because  PI_FIFO_RESET is writing and after fifo.CPReadWriteDistance will be setted to 0.
To Prevent that, I've Implemented AbortFrame function in the CommmandProcessor. It should fix overflown because of that. 
Note: There is other issue (Issue 2846) where the fifo.CPReadWriteDistance is negative too but the effect is different.
I'm working to solve this.
