Obviously, I can't do anything with the vmcore without the matching kernel (and
perhaps modules).  Also, kgdb and libkvm.so from the matching system can be needed.

Perhaps you could try examining the devfs_rule_run frame to give a start?
Like listing the source code line and examining all local variables.

Thank you.
