[SOLVED] Proxmox PCIe passthrough for TrueNAS

Hi there,
I'm doing something quite trivial I have this controller and 4 HDD disks attached to it:

root@sofx1010pve3307:~# dmesg |grep 2008
[    0.256490] DMAR: dmar0: reg_base_addr fed90000 ver 1:0 cap d2008c40660462 ecap f050da
[    3.309755] mpt2sas_cm0: LSISAS2008: FWVersion(, ChipRevision(0x03), BiosVersion(

For sure the PCI passthrough is working correctly because I'm able to see all the HDDs in the VM but - I perform the installation, reboot the server and when I try to boot it says:

Guess what, if I remove the PCI passthrough it boots like charm ;-))))

So far I've tried to change the type of the disk from Virtio to SCSI - no luck.

Here is the config of the VM:

root@sofx1010pve3307:~# cat /etc/pve/nodes/sofx1010pve3307/qemu-server/156.conf
#SERV%3A TrueNAS Scale Storage Appliance, HBA passthrough
