Thanks Tarmo! I've added the change, looks like it's booting with only 2667 kbytes.. ==> sysctl: vm.min_free_kbytes=[2667] ==> sysctl: setting: [sysctl -w vm.min_free_kbytes=16384] vm.min_free_kbytes = 16384 https://github.com/RobertCNelson/boot-scripts/commit/8257ea5800adb6cdc8d4ca3230eac44ae7c54eea Now running on one of my very (early alpha) picky bbgw, that usually doesn't want to flash the eMMC..
