Better than I can. There's a work-around in the kernel for pre rev-8 hardware that ensures every time the blt ring is advanced by the CPU, the first command executes a batch buffer. So the hardware is obviously quite broken. This workaround doesn't work perfectly, and the GPU will still lock up when executing commands out of the blt ring from time to time. As pre rev-8 hardware is all pre-production, the workarounds should be removed From the driver and all acceleration disabled. -- keith.pack...@intel.com
