Sometimes when I update a Drupal module or core install, some CVS files are removed - namely Entries.Log files. When you go to svn up your changes, it will complain saying that there are files in your repository that no longer exist in your working copy (signified by the ! mark). To get rid of these, try using the following bash script (you can put this in your .bashrc file in *nix, if you're using the bash shell of course):

For example, try:

svngrep '^!.*Entries\.Log' 'rm --force'

This will run an svn status, filter out all but the missing Entries.Log references and remove them! Run svn status again and the inconsistencies should be gone!
