Any hints to overcome this issue?
I have seen similar problem when using UFS 2.0 controller. The ufs driver currently doesn't set correct command type field in UTP transfer request descriptor (bit 31:28 in DW0) for UFS 2.0 controller. I checked that your DesignWare UFS driver handles it correctly, so please try with that change. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
