It should be easy to get a stack trace using SGI debugger (http://reality.sgi.com/slurn_engr/). It allows you to generate stack traces from arbitrary processes. I have to say that having it into the kernel wouldn't be a so bad idea... (it was GPL'd if I remeber well :).

The down failed may happens if the loop file has holes for example. No idea yet about wait_on_super deadlock though :).
