try the linux_kdump... the dtrace might have problems on its own as it
is really new code...

a LOR could lead to a deadlock not a crash.... if you still have the ktrace.out
I believe you can put it on a web and we can run our own linux_kdump on it to
see what happened. can you make that available?
