Hello,
GNU tar 1.23: --verify used with --listed-incremental (-g) when tarring an NFS
filesystem (Linux 2.6.18) results in a "Contents differ" error. Either option
can be used alone successfully. Together they result in an error and a non-zero
exit status.
In this test, machine1:/home is mounted on server1:/n/machine1/home. The
blocksizes for the two filesystems are 4096, and the kernels are CentOS:
2.6.18-164.11.1 and 2.6.18-164.15.1, respectively. Default NFS export
parameters were used.

(I don't use this directory.) This error vanishes if either -g or --verify (or
both) is removed.
