You know that I know that and I Know that you know that I know that :-)

Very helpful , thanks,
I have almost the same setups as you(SSD:filesystem, uSD:v1.14, PL011(&HDMI) ),
`tried SSD with and without external power...
Very happy to hear that we now have 2 machines booting in acpi-mode(Unfortunately, my two gadgets are not included for now :-)

that brought me to the idea to test different loaders and one of it „succeeded“ in a loop session 
but WITH detected controller(VL805)… that’s so strange and not logically reproducable(but repeatable),
happened only on the 4GB(not on 8GB) with the left two USB-slots… see dmesg at the end of this message…

That’s the VL805, which was not detected with me(except the on the here attached  dmesg).
On the 4GB, the VL805 has an own eeprom while rpifoundation removed that own eeprom on the 8GB.

Holy sh*t, it gets stranger and stranger with this gadget..tss..
Did you leave anything from the files of an msdos-partiton on the SSD?
If yes, try to remove them all (except the efi)

Hm, didn`t see that on mine afair, `will think about that...

O,K, thank you all !

, `have no idea at the moment except changing the boot-hardware(USB-stick or so…)
