While investigating the issue with my SATA3 SSD drive being recognized as SATA2 (for some reason had to change SATA ports to fix it) I noticed the following messages when I run:
$ dmesg | grep ata3.00
[ 0.980592] ata3.00: ACPI cmd ef/10:06:00:00:00:00 (SET FEATURES) succeeded

My architecture:
$ uname
3.13.8-1-ARCH
My concern is the line where it says that system failed to get NCQ Send/Recv Log Emask 0x1
Is this something I need to be concerned with?
My system is Asrock Extreme4 mb with SAMSUNG MZ7PD128HAFV-000H7 SSD SATA3 drive on Arch Linux OS.
Update 1
I run SysLinux on my machine and below is the output of the same command (no failure messages):
root@sysresccd /root % dmesg | grep ata3

I compared SATA power profiles on both OSes under /sys/class/scsi_host/host(0-7) and they set to max_performance.
What else can I check on both OSes and configure Arch so that this failure message would go away?
Update 2 Looks like this issue only appears in newer kernels...
I tried with Ubuntu Live CD 12.04, 13.10, and 14.04: I was able to see this issue in 14.04 but not in other 2 versions.
I then run diff for the kernel config files but I can't figure out the exact change that affects me...
