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

[    0.981227] ata3.00: configured for UDMA/133

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...

Ubuntu 13.10 kernel config file

Ubuntu 14.04 kernel config file
