I had this happen to me constantly while doing make cleandir in /usr/src here,
which resides on an LFS slice. I stopped using LFS for a while, and recently
started again, but I created the filesystem with bsize=fsize (8192), and have
not had any problems with it since. I think the bsize != fsize was what was
causing the issue, and Conrad had suggested to me a while back that I use
the same bsize and fsize.
