There are two possibilities that I can think of - either the script
/var/www/html/lxr/bin/genxref does not have the correct permissions to
allow your userid to access it, or some file under /usr/src/linux does
not have read access to your user.  To check if the permissions are ok
on genxref, use ls -l and check that either (a) you own the script and
the user permissions are r-x, or that your group owns the script and the
group permissions are r-x, or that all users (others) have r-x
permissions.

You can see if some file under /usr/src/linux is causing the problem by
looking at the output of 'strace genxref /usr/src/linux'.  This shows
the system calls being made, and should show you what file access is
causing problems.

The final possible reason (though unlikely) is that your copy of genxref
comes from a windows machine, and thus the line endings are wrong.  If
'perl /var/www/html/lxr/bin/genxref /usr/src/linux' works but executing
it at as command doesn't then this is a likely cause.
