Just to make it clear, Centos on MacchiatoBin works with the normal installer and AltArch image without any setup quirks - we just need to compliment the ACPI support for remaining interfaces in the Linux mainline first (Network and SD/MMC controller). FYI, it is likely that we add ACPI-support information to the mainline Linux support matrix for Marvell SoCs: https://elinux.org/Marvell_EBU:Mainline_Linux Best regards, Marcin
