--- Comment #1 from Theodore Tso <tytso@....edu> ---
These errors have nothing to do with relatime.  

You can control whether the last access time is updated on every single read
(which is a performance disaster, but required by POSIX) using the mount option
strictatime.  You can also set the last access time to never be updated using
the mount option noatime.   The default, relatime will update atime if it is
more than 24 hours out of date, or if atime < mtime. 

None of this has anything to do with the NCQ error, which is coming from the
device, and not the file system.
