Hi, Pino:

Thanks for your hint.
I think we got the key:

on the machine fail:
we lack of lines like:

kernel/drivers/char/hw_random/amd-rng.ko:
kernel/drivers/char/hw_random/via-rng.ko:
kernel/drivers/char/hw_random/virtio-rng.ko: kernel/drivers/virtio/virtio_ring.ko kernel/drivers/virtio/virtio.ko
kernel/drivers/char/hw_random/tpm-rng.ko:
kernel/drivers/char/tpm/tpm_nsc.ko:
kernel/drivers/char/tpm/tpm_atmel.ko:
kernel/drivers/char/tpm/tpm_infineon.ko:
kernel/drivers/char/virtio_console.ko: kernel/drivers/virtio/virtio_ring.ko kernel/drivers/virtio/virtio.ko
...

which existed on the machine works fine.

It works fine now.

But why we make initrd only depends on modules.dep?
