The following didn't make it to gnats. (Things need to be sent to
gnats-bugs as well as or instead of netbsd-bugs.)
Also, 38778 was closed as a duplicate of 38265.

| On a freshly booted system there is no problems to see files under /kern;

This symptom may be triggered intensive file access, and in
my case rsync -aH /m/NFS-HOST/ /local-dir/ with having
/m/NFS-HOST at large size. It is really 180GB for here.
It only needs two minutes to reproduce the problem.
But just find src -newer tarball.tgz or find src tarball.tgz may
be the key.
I have tracked down this problem, and it seems to me
that the changes in the range of
2008/01/24 17:30 UTC - 2008/01/24 18:00 UTC
is the key to this behavior.
Also when I rebooted at 2008-01-24 18:00 kernel, I was getting
unmounting file systems...panic: unmount: dangling vnode
In this range: following commit seems to be very suspicious:
