Hi, community

       I meet a problem of SATA 

       hardware :  Imx6q core board + carrier   

       OS :  LINUX 3.0.35  

       SATA device :  I tried  both  HDD and SSD

       when power on we can see this information from serial port: 


Uniform Multi-Platform E-IDE driver
ide-gd driver 1.18
ahci: SSS flag set, parallel bus scan disabled
ahci ahci.0: AHCI 0001.0300 32 slots 1 ports 3 Gbps 0x1 impl platform mode
ahci ahci.0: flags: ncq sntf stag pm led clo only pmp pio slum part ccc apst
scsi0 : ahci_platform
ata1: SATA max UDMA/133 mmio [mem 0x02200000-0x02200fff] port 0x100 irq 71
GPMI NAND driver registered. (IMX)


and later:

ata1: SATA link down (SStatus 0 SControl 300)


I use external power for HDD, so power is stable.
