There are only three changes to mvsas between 3.5 and 3.7: 95ab000 [SCSI] mvsas: Fix oops when ata commond timeout. cca8501 [SCSI] mvsas: remove unused variable in mvs_task_exec() f0bf750 [SCSI] libsas: trim sas_task of slow path infrastructure And of those, I can only see f0bf750 being significant, if you could revert it? After that, it's probably a bug introduced into libsas, which has a bit more of a complicated history from 3.5 to 3.7: 8d8e7d1 [SCSI] libsas, ipr: cleanup ata_host flags initialization via ata_host_init 303694e [SCSI] libsas: suspend / resume support 2955b47 [SCSI] async: introduce 'async_domain' type f0bf750 [SCSI] libsas: trim sas_task of slow path infrastructure a494fd5 [SCSI] libsas: drop sata port multiplier infrastructure b17caa1 [SCSI] libsas: fix sas_discover_devices return code handling 26f2f19 [SCSI] libsas: continue revalidation b2311a2 [SCSI] libsas: sas_rediscover_dev did not look at the SMP exec status. e7db822 [SCSI] libsas: use ->lldd_I_T_nexus_reset for ->eh_bus_reset_handler 9524c68 [SCSI] libsas: add sas_eh_abort_handler 5db45bd [SCSI] libsas: enforce eh strategy handlers only in eh context 36fed49 [SCSI] libsas: cleanup spurious calls to scsi_schedule_eh e4a9c37 [SCSI] libata, libsas: introduce sched_eh and end_eh port ops So I'd try a bisection rather than trying to revert individual commits in there.
