Monimod doesn't boot properly on crate power-on
However when connecting DSUB cable to an already running crate it boots properly.
It seems there is a spurious shdn_n generated by the System Board (see scope screenshot) on crate startup (which might be coming from a spuious pwr_cycle request - to be investigated). Anyhow, even this spurious shdn_n should not freeze the monimod, it should always react properly to the shutdown request.
