NUC9VXQN BIOS Update 0061 regressed and booting with AMD GPU stuck again

[EdwardX]

Previously I had boot issue with AMD 5700 on NUC9VXQN. BIOS update 0054 fixed the issue for me: https://community.intel.com/t5/Intel-NUCs/NUC-9-Pro-Kit-NUC9VXQNX-boot-loop-with-AMD-RX-5700-only-happens/m-p/1204401#M75945

However, today, after I upgraded to BIOS 0061, the same boot issue has comes back. The currently symptom is that:

• BIOS video setting:
  • Primary Graphics: Auto, IGFX: Auto. (This is equivalent to disable IGFX during boot)
    • If HDMI is plugged into AMD 5700 during boot, the boot stuck at NUC logo. The system power cycle itself after about 60 seconds.
    • If HDMI is not plugged during boot. The system boots fine. I wait for ~30 seconds and then plug in the HDMI cable into AMD 5700, everything works in windows.
  • Primary Graphics: IGFX, IGFX: Enabled. (Force IGFX to be primary)
    • If HDMI is plugged into AMD 5700 during boot, the boot stuck at NUC logo. The system power cycle itself after about 60 seconds.
    • If HDMI is plugged into IGFX only during boot, it boots fine. After booting into windows I can plug HDMI into AMD 5700 and it works.
    • If HDMI is not plugged during boot, it boots fine. After booting into Windows, both IGFX and AMD 5700 shows up in windows and both work fine.

So, as long as AMD 5700 is not hooked to a display during boot process, it boots fine and AMD 5700 works fine in windows. But if AMD 5700 is hooked to a display during boot process, it will get stuck at NUC logo.

Please do not tell me that it is compatibility issue. - This issue was fixed with BIOS 0054 and now it is back again after I installed BIOS 0061.

EdwardX, Thank you for posting in the Intel® Communities Support.

For this scenario, just to confirm, is there any particular reason why you did the BIOS update to version 0061?

In the following link, you will find additional suggestions to try to fix the problem between the Intel® NUC 9 Pro Kit - NUC9VXQNX and the AMD 5700 card, once you get the chance, please let us know the results:

The first link you posted was about eGPU, but I'm NOT using eGPU enclosure. The AMD RX 5700 is plugged into the PCI-E 16x in the NUC 9 Pro.

I will attach a new SSU report when I have time.

If an old SSU report that was taken a long time ago works, you can find it from my previous post. There is no hardware changes: https://community.intel.com/cipcp26785/attachments/cipcp26785/nucs/75192/1/ssu.txt

EdwardX, Thank you very much for providing that information.

"I will attach a new SSU report when I have time." Perfect, no problem at all, take your time and once you get the chance please provide the most recent SSU report so we can have the most accurate information about your system.

Even though BIOS version 0061 is already installed, please try a BIOS recovery to that same version following the instructions in the link below, once you get the opportunity please let us know the results:
