5.1    SAS - I_T nexus loss for NAKs or lack of credit [Elliott]

the initiator in this circumstance. Rob agreed to drop the proposal.

5.2    SAS Port layer rewrite (02-393) [Elliott]

Rob Elliott presented 02-393r0, SAS Port layer rewrite. In the process of
incorporating the port layer into the SAS working draft, Rob found both

affects both SAS and SPC-3. He received input and agreed to defer
consideration of his proposal.

5.4    CRC on Frame Header [Roberts]
