http://bugzilla.kernel.org/show_bug.cgi?id=14831 Summary: mptsas - Use of ATA command pass-through results in unreliable operation - drive / controller resets Product: SCSI Drivers Version: 2.5 Kernel Version: 2.6.26 - 2.6.31 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: tim@xxxxxxxxxxx CC: kashyap.desai@xxxxxxx Regression: No On Debian 2.6.26-2-amd64, and mptsas 3.04.13 from scsi-misc-2.6.git, use ATA command pass-through on LSI SAS1068 and SAS1068E may result in: . Device resets . Device offline . Controller offline (only observed on 2.6.26) The problem seems to occur far more frequently with the SAS1068 (PCI version). I haven't verified whether any data loss is occuring, but this does at least seem to be a possibility.
