I can't reproduce this. I wonder if you need a specific cramfs file. Could you make yours available somewhere, or attach it to this bug please?
Created attachment 124967 [details] cramfs test file here is the cramfs file...
this is fixed in the 2051 kernel at http://people.redhat.com/davej/kernels/Fedora/devel (That'll be the final FC5 kernel)
