*** Bug 185476 has been marked as a duplicate of this bug. ***
For these and the other various PRs you opened recently, you need to remove the 'grep 0x' from the 'nm -n' output. That removes most of the useful symbols and isn't helpful. In addition, far more useful would be to get stack traces, especially if you have core.txt.N files, the kgdb stack trace in that file would be the first thing needed to look at any of these. As I mentioned on another bug, a dmesg from this machine wouldn't hurt either, but I doubt that either ed(4) or xl(4) is relevant.
