        umapfs keep making my kernel panic in deadlocks

        stacktrace isn't provided due to that savecore doesn't work for me
        (see kern/13076), and the ddb output keep sending


        nfs-mount and umap mount your netbsd build tree (I map one uid, not
        a gid).

        cd ${umapS}/arch/i386/stand
        while true ; do make -j12 && make clean ; done

        wait ~2-30 sec and se the kernel reclaim the first vnode in
        getnewvnode() and then die in a deadlock.


        Not a clue. I'm not a friend of ddb and depend on that I have kgdb
        or coredumps to diagnose my bugs. And since I don't have a build
        enviroment for this computer I haven't tried yet.

        I might have a chans to diagnose the bug when I get back to my
        debug computer.
