          Issue #1 closed. Running the same test triggers a different bug every time, giving varying levels of suckiness.

              A game is closed source but at least it doesn't do anything at kernel space.

                That is security issue then, opensource radeon driver uses closed source firmwares

                  How many complex devices that need firmware actually have open source firmware?

                    And your hard drive uses firmware. And monitor. And mouse. And so on. So it basically comes to the question what if could do. GPU lacks network connectivity and in modern systems if it would try something nasty like DMA to unrequested space, IOMMU would engage and illegal access will be caught. Can be an issue on old systems without IOMMU though. However, its not like if relatively small firmware can hold logic to patch arbitrary system. So I guess this problem is limited and not fundamentally worse than, say, HDD firmware (which haves all chances to return you wrong sector, potentially hijacking execution flow of kernel or application).
