Looks like the mvsas driver uses libsas, so it likely relies on libata for SCSI-to-ATA translation. Will have a closer look. I also have other HBAs using the pm80xx driver that is similar. Will do some more tests with that. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
