These are the user-space programs:

root@...za:~# LC_ALL=C dmesg -T | grep 'SCSI ioctl error' | awk '{
print $11 " " $12 }' | sort -u
prog ata_id
prog hdparm
prog pool-udisksd
prog smartctl
prog smartd
prog udisksd

These are cmd #:

root@...za:~# LC_ALL=C dmesg -T | grep 'SCSI ioctl error' | awk '{
print $9 " " $10 }' | sort -u
cmd 85,
cmd A1,
