I found evidence of a ACPI+DeviceTree vs. just DeviceTree difference via the boot -v output: note the #Pages of the BootServicesData and the prior ConventionalMemory area. ACPI+DeviceTree: ---<<BOOT>>--- GDB: debug ports: uart GDB: current port: uart KDB: debugger backends: ddb gdb KDB: current backend: ddb WARNING: Cannot find freebsd,dts-version property, cannot check DTB compliance Type Physical Virtual #Pages Attr . . .

B) Just DeviceTree got a: (probe0:umass-sim0:0:0:0): INQUIRY. CDB: 12 00 00 00 24 00 (probe0:umass-sim0:0:0:0): CAM status: CCB request completed with an error (probe0:umass-sim0:0:0:0): Retrying command, 3 more tries remain sequence; ACPI+DeviceTree did not. C) The /dev/gpt/CA72USBufs clean/free/frags line's figures were somewhat different. D) The time line's figures (after the "Starting background file system checks in 60 seconds." line) was somewhat different. That is it for boot -v output differences (non-debug build). I've switched the RPi3 EDk2 microsd card to use ACPI+DeviceTree. === Mark Millard marklmi at yahoo.com
