check your PM box I have sent you another standalone test kernel. New are that I eliminated the initialization of usb part (not necessary for the cloudbox) Modified the leds driver, thanks to your test i found that also nwsp2 lite would have had this problem.
Lats I eliminated the initialization of I2C, it is used on the other Lacies to access the eeprom on board, seems the cloudbox doesn't have it. At least in GPL code of Lacie I do not see the initialization of I2C. Looking to the erro mesage in your dmesg output it seems indeed to be the case that is not there in the cloudbox.
We will need some adaptations in the fvdw-sl firmware itself for the cloudbox such as not loading modules for usb ports.
Would be nice if you can test this kernel and post dmesg output to see if all error messages are gone now.
