Just synced with my colleague, the issue could be caused in your kernel configure of pre-launched VM: CONFIG_SERIAL_8250_DETECT_IRQ=y
Please confirm.
Thanks Minggui

Yes, with the vm terminal I meant ACRN console. After the boot (vm_console 0), the console becomes unusable but the kernel starts correctly. |
