I assume that the internal flash memory is being read much too quickly, but all services have not started yet. A pause would then have to be inserted in the rc.local before mounting the SSD.
mount /dev/nvme0n1p1 /media/nvme
#mount nvme drive
#mount nvme drive
sleep 5 && mount /dev/nvme0n1p1 /media/nvme
if there is a pause of about 5 seconds before the mount command is set, the SSD will work after booting the MCU-2.
This helps with super-fast SD cards or internal flash memory of the Orange PI 4 LTS
