Clean OS (Debian), OpenMediaVault and other "firmwares"

Log after upgrade Stretch WdMycloud Gen1

I post the logs of WdMycloud gen1 after a stretch upgrade, the device start, green led, but no response in ssh.

If an advanced user could take a look, it would help me a lot.

Can be a track : pfe_firmware_init: request firmware class_c2000.elf failed
pfe: probe of pfe.0 failed with error -110

Thank you in advance.
