--- Comment #2 from TJ (linux@iam.tj) ---
This could be a power management issue:

  vfio-pci 0000:02:00.0: Unable to change power state from D3cold to D0, device
inaccessible

Could you add the outputs of these commands?

# detailed PCI device info
sudo lspci -vvnnk

# power reset methods of PCI devices
find /sys/devices/pci0000\:00/ -name reset_method | while read -r f; do echo -e
"$f = $(cat $f)"; done
