Well, this is odd.  I've changed nothing but the ext2fs option in my
kernel config file (since, apparently, I was already builing a kernel
with gdb debub symbols), and now I have no problems when starting up or
shutting down.  So apparently this is only a problem when using the
ext2fs kernel module.
