There is no error message from the dmesg. But there do have lots of

All I see now is a completely blank screen right after the grub screen
(with BIOS VT-d on, and with intel_iommu=on..etc boot options). There
seems to be no logging happening (syslog has no entries for these boots).
The blank screen persists and there is no response from any inputs. I
waited 3-5 minutes and then rebooted manually.
You may need to config the serial port to get the boot message. Without
enough message, it's hard to tell what is wrong. Alternatively, you can
remove all additional devices to see whether system can boot.
