I was just asking if you were changing them in case it was to some 
values where the login should fail like if you initially setup both 
boxes to always want CRC32CS, but then switch to where we always wanted 
CRC32C on the initiator but never on the target.

I did and tried the ones that did not work, but they worked for me with 
the git head iscsi code and with the svn head iet code.

Is that with the open-iscsi.org releases or fedora/RHEL/Centos ones? I 
disabled data digests in the fedora/RHEL ones because they were causing 
some problems.
