Yeah, I see that as well even without enabling the IOMMU.
root@(none)$ [ 163.974907] sas: Enter sas_scsi_recover_host busy: 222 failed: 222 [ 163.981108] sas: sas_scsi_find_task: aborting task 0x000000005c703676 root@(none)$ root@(none)$ [ 185.963714] pm80xx0:: pm8001_exec_internal_tmf_task 757:TMF task[1]timeout.
I figured that it was a card FW issue as I have been using what I got out the box, and I have no tool to update the firmware on an arm host.
It seems that SSP and STP commands are not completing for some reason, from the "busy: 222" line.
