We had a similar problem under rehdat enterprise 3, but the filesystem
size for AFS was negative. Turned out to be a problem between the kernel
version and the libc version. The following patch (against 1.2.11) correct
the problem for us.

@@ -325,6 +325,8 @@
     stat.f_fsid.val[0] = AFS_VFSMAGIC;
     stat.f_fsid.val[1] = AFS_VFSFSID;
     stat.f_namelen = 256;
+    /* to fake the user space f_frsize member being 0 */
+    memset(stat.f_spare, 0, sizeof(stat.f_spare));

 #if defined(AFS_LINUX24_ENV)
     *statp = stat;
