Hi,
I am having issues upgrading PVE from 7.4.20 to 8.4.5. Everything appears to run fine until I reboot and lose access to my LSI controller with the error message.
Code:
kernel: vfio-pci 0000:02:00.0: BAR 1: can't reserve

The disks attached to the LSI cannot be seen in the WebGui after the update.
Iommu was enabled fine and working with the device passed through to a TrueNAS scale VM.

I've recently had to rebuild my main PVE server and have done a fresh install of 7.4-20. (This is the latest version I could get installed as the 8.4 installer kept freezing). I previously ran 8.4.1 on the same hardware without issues. I have reinstalled now as needed the VM up to get access to the data,

Has any one had a similar issue of any idea what is going on?
