Hi, Just noticed a lot of messages in my logs, though the system seems to be working fine.

Here are the references for the SATA phy : 04:00.0 SATA controller: Marvell Technology Group Ltd. Device 9183 (rev 14) 04:00.0 0106: 1b4b:9183 (rev 14) I tried fixing this problem by adding libata.force=1:noncq to the command line, it didn't help. Any idea?
