PCI passthrough - stop working after VM reboot.

[intonet]

Hi!
My PCI device working well in virtual machine until reboot. To work again i need to restart truenas host.
I tried to detach device by command:

virths nodedev-detach --device pci_0000_00_14_0

but devices immediately back to host system
dmesg:

Sorry
I have running trunas scale on Intel pc with i5 CPU.
Version: TrueNAS-SCALE-22.02.3
Problem occurs on my all VMs. I tried on pure Debian buster and homeassistan OS. Is no matter the reboot was triggered by system or by truenas gui. Stop and start VM does not restore PCI devices on VM too. Only restart truenas host made PCI passtruough working again.

Please read the forum rules. They even specify the level of detail for the hardware that is required (yours is far away from that). Plus a ton of other useful information, that will help you better help.
