Stop 0x119's are quite rare, so you probably won't debug one of these bugchecks, but if you do find yourself in this situation, then you've come to the right place because in this post I'll be talking about Fence IDs. Just as a pre-warning, I will not completely discuss the internals of DMA (Direct Memory Access). That will need to wait for a separate topic. I have yet to explain the Heap fully too.
