Not a very useful thing, that. Ah -- oh well. OK so yeah you have an interrupt storm, this is evident. Do you think there is a way you can try to trigger the interrupt storm so it happens < than after 7 hours or however long its taking you? If so then it'd be good to get your debug out using the interrupt debug. If that's not useful then we can enable all debug stuff (file will be huge). Try turning on the microwave, turn on all your bluetooth devices, use your 2.4 GHz wireless phone, use your xbox 360 controllers and ps3 controllers all at once :D Luis
