I've been trying to do some research, but have not found a patch to the problem. The machine locks up entirely, no debugger or anything, so i'm at a bit of a loss not having debugged these before. is it expected that one can get a core or panic or into db at this time? As you can imagine, searching for lock order reversal returns a lot of hits. is it 'kern/60581: lock order reversal'? this indicates its a 'known false positive'... But my machine locks up solid. So i think that's not it.
