By hard locks you mean you can't ssh in the computer ? There is a bug in my patches which lead to mutex/irqlock deadlock i don't understand it yet but i can happen and might explain your hardlock. Once i fixed those i will send new versions of the patches. I plan to latter add infrastructure to capture faulty instruction but this isn't yet done and this will likely need huge pile of code.
