Re: Asking for help to debug xen efi on Kunpeng machine

[Jiatong Shen <yshxxsjt715@xxxxxxxxx>]

Hi Stefano,

   Thank you very much for the reply. I do have access to serial but the machine is near my work space right now, so 

I might need some extra time to go to datacenter first. I'll let you know if it is indeed working.   

  Thank you very much again.

Best regards,.

Hi Jiatong,

Do you have access to the serial? If so, it is possible that the boot
is actually successful and it is only the screen initialization the
problem.

If kunpeng 920 is a UEFI/ACPI machine, we know that there are issues
with screen initialization.

Cheers,

Stefano
