This is my guess:
It’s just that by the time the shell is ready, the HA is not. So in the console it done waiting and said “not ready”.
By the time you type in banner
, and hit the enter key in the same console, the HA is ready, so you have regular prompt.
@imola.zhp @jemn1 @chat - what’s your HW running HAOS, and roughly how long between your “not ready” and banner
command?
