Hello Stefano and Julien,
Could you provide more insights for debugging? I tried to connect to
serial console through ipmitool sol activate and enabled ACPI, I do see
some logs but the machine is still stuck. BMC video screen is still not
responsive and black out.
Thank you very much for the help!
Best Regards,
Jiatong Shen
