About a SATA device detection error for i.MX537

Our customer reads the kernel image and rootfs of Linux from SATA.
Bootloader is booted from SD card.

 

Usually, Linux starts correctly.
However, it fails one out of ten times.

 

Error is "No port device detected!".

 

When an error occurs,
According to the log, a state seems to be 'phy not ready'.
I attach the log of an error and a normal operation.

 

I think that this is applied to errata "ENGcm11084-5."
However, a workaround of this errata is "None".

 

Is there any method of avoiding such an error by software?

 

May I have advice?
