Proxmox 6.2 GPU Passthrough Issue

I was able to passthrough a FirePro W2100 to a VM on Proxmox 5.4 but after upgrading to proxmox 6.2, I am getting the fallowing issue from the host when the VM boots. Any help would be greatly appreciated.

What does your grub file look like?

nano /etc/default/grub

# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_CMDLINE_LINUX=""

# Disable os-prober, it might add menu entries for each guest
GRUB_DISABLE_OS_PROBER=true

# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

# Uncomment to get a beep at grub start

Okay fair enough…

Should have asked initially, but what is the rest of the hardware in the system?

Also what’s in your /etc/modprobe.d/vfio.conf

Its an Intel® Xeon® CPU E5-2667 v2 @ 3.30GHz (2 Sockets) and i have an LSI HBA card installed. I have played around with other video cards and still having the same issue. The only thing that i can remember changing is the OS. I don’t believe that i changed the BIOS any from when it was working before the Proxmox upgraded.
