I wasn't able to collect any additional information when I observed a hang, because I didn't have access to another system on the same network to ssh in (though based on my observations, I'm confident it was only the GPU. The system responded to sysrq+k, though the console was never properly restored).
If there is another way other than ssh to get a text login on the system when it is in this state, I would like to know so that I can try it if it happens again.
