UNRAID won't boot with the vfio tag

Hi, I had a fully working system until I decided on a dreaded BIOS update.


I downgraded back to my original BIOS which is a feature of my motherboard. But no matter what I do, even with a fresh install of UNRAID -- the moment I do a GPU passthrough attempt, my UNRAID install won't finish booting.


The moment I boot without the vfio tag, things spring back to life and I get the DHCP handshake. What gives? :(


I've included a copy of the syslog information. After vfio takes over my display, I rely on pinging the server with no response to know things aren't coming back to life. I typically have UI access within a minute or so.


Here's my syslinux.cfg. Booting into GUI mode works. Booting into headless mode won't.


default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label Unraid OS
  menu default
  kernel /bzimage
  append vfio-pci.ids=10de:1b06,10de:10ef,10de:17c8,10de:0fb0 initrd=/bzroot
label Unraid OS GUI Mode
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui
label Unraid OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Unraid OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

Downgraded to 6.7.2 & disabled UEFI boot. Now things work.


I've yet to work out the root issue, but I think it's UEFI boot.




Upgraded to 6.8 rc5 with success. Upgraded BIOS again. No issues. Seems the problem was UEFI boot.
