Subject: About [AMCC 460EX/canyonlands board] Synopsys DesignWare Cores (DWC) 
	SATA host driver

Mark,
  I found that the current sata_dwc can only work on
DENX-2.6.25-stable, and have problems in DENX-2.6.26, 27, 28,
29(master),
the boot errors is as the following, I hope you and AMCC staff submit
it into mainline soon, thanks.

there is also some other boot panic kmsg, I will reproduce it tomorrow.
