I tried a couple of input files without luck. Sometimes, it's easier to get into DDB if you're using a serial console and serial break -- could you try that? When the system is stuck in a tight spin while holding Giant, for example, the console debugger may not be able to generate a useful break. This will improve if we can get the system console to get less involved in Giant.
