I've seen other forms of these file-mixing phenomenoms, which is probably
the same underlying bug:
http://mail-index.netbsd.org/tech-kern/2003/09/05/0002.html

It has also been seen by someone else on completely different harware, which
rules out a driver or machdep issue. He also had a file system full condition
just before the problem. On my server I didn't have this, but I have quotas,
and the effect it probably the same at the filesystem level when a user is
overquota. Both of us have NFS in the game, but I guess in your case
/ and /usr are not NFS exported ?
