Yes, errors are on all 5 disks in the same RAIDZ pool. No problem on other disks in different pool but on the same SAS cable. So maybe I only had bad luck with that disks.

You may need to 'pkg install system/storage/sasinfo' first. I've got the same hba (not sure of the firmware rev.) but ran into the exact same issue. My issue was the power supply and the small gauge wires used to power the drives. I installed a new power supply w/ the same wattage but heavier wires and all my issues disappeared. I stumbled upon the solution by connecting a separate power supply to one of the drives and hot wiring the MB connector to power it on (i.e. green wire to any black w/ paper clip). All the issues disappeared for the drive on the separate power supply while the other continued to have issues. All my drives have run error free for a months since the new power supply. YMMV!
