Greetings,
Between version 1.3 and 1.4 there were some several changes to cramfs ... and unfortunately, there is
some pretty broken code in cramfs/inode.c. Specifically, some
new bit manipulation macros
were added that hose the fs from the get-go. Anyway, for those who use cramfs, here's a quick fix:<div class='quotetop'>QUOTE </div>
