I have sometimes strange sata errors when I mount a xfs formatted logical volume on a luks encrypted volume group. It's a company laptop and a company rule is to crypt the SSD. On 100 mount's fail 5-20 times. If the lvm is mounted I can work the whole day without any errors, so I don't think it's a hardware error.

The ATA errors on mounting occur only with xfs formated lvm's, ext2-ext4 produces no errors. Here is my test to reproduce the errors:
Code:

lvcreate -L 4G -n test zalando
mkfs.xfs -L test /dev/zalando/test

for I in `seq 1 100`
do
   logger "Nr $I of mount unmount:"
   mount /dev/zalando/test /mnt/backup/
   logger "mount return code: $?"
   umount  /mnt/backup/
   echo $?
done


and here is the results in my syslog:
Code:

Since NCQ shows up in some of your error messages, you could try disabling NCQ using kernel parameter libata.force=noncq

Apart from that I don't think ATA errors are related to LUKS/XFS. I'm running XFS on LVM on LUKS on MD on SSD myself, zero issues.

Also run a smartctl -t long just in case.
