Does this still occur on a fresh build?

That sounds similar as the issue as discussed in

Root reason: dropbear has been compiled with ecdsa key support, but there is a zero-byte ecdsa key file /etc/dropbear/dropbear_ecdsa_host_key (instead of either no ecdsa key file or a proper key).

So, possibly this is just dropbear reacting badly to invalid key.

(fixes available in and , verified in )

Ps. If the original reporter was using Arokh's build, that has now been fixed.
