Ah, that was in the second patch (I didn't look at that. My fault). I didn't see this description in the comments. But you are right, it is very close to what I did too. But before we add this to -rt, it will need to probably need to be tested quite a bit more. Especially since this is more to help us developers than to help end users. I would like to see something like this eventually make it into RT. Just because there has been too many times that this would be useful. For now I just use the NMI watchdog and soft lockup detect. But those are very limiting. > > Hope that helps to clarify.
