[video=efifb:off,vesafb:off not working in UNRAID 6.10-rc1]

PS: I used to be able to bind VFIO devices using the vfio-pci.ids in GRUB, but that does not work anymore in unraid 6.10, so the VFIO-PCI plugin (integrated with 6.10) is the only way to go, but that solution freezes my PC.

[video=efifb:off,vesafb:off not working in UNRAID 6.10-rc1]

Hi all!

 

I'm trying to fix a vfio binding issue. I have 2 GPU's in my server, and I'm able to pass the 2ND GPU to my VM's with the integrated VFIO-PCI plugin that comes with unraid 6.10. However, when I try to bind the 1rst GPU (checking all 4 NVIDIA devices, just like the 2nd GPU) it will freeze on boot when it comes to vfio-pci.... in the boot sequence. 

 

I read that disabling the framebuffer can help the system bind boot device GPU's, so I'm not trying to disable the unraid framebuffer when it boots from GRUB in hopes it will allow the 1rst GPU to bind as well instead of just freezing the PC on boot.

 

I have tried this in my GRUB config, but to no avail, the framebuffer is still visible no matter what I do. Has anyone had any success with these methods on NVidia cards to disable the video output on boot?

 

label Unraid OS
  menu default
  kernel /bzimage
  append initrd=/bzroot pci=noaer pcie_acs_override=downstream,multifunction  video=efifb:off,vesafb:off,vesa:off

 

When I boot I get this, even with the video=efifb:off... Here is a screen shot of the vfio-pci freezing. I've also attached a diagnostic or my server (when I don't try to bind the 1rst GPU).
