Proxmox 8.1.3 Kernel 6.5.11-6 - i915 Setup Error not enough MMIO resources for SR-IOV after reboot

Hi, I did try following the steps that you have shared but once the node is rebooted I'm getting the following errors:

I'm running a Proxmox 8.1.3 with Kernel 6.5.11-6.

In addition, after the module compilatoon, I got the following file generated: /var/lib/dkms/i915-sriov-dkms/6.5.11-6/6.5.11-6-pve/x86_64/module/i915.ko

However, in the log file i saw a couples of warnning as you can see below:

`
make.log

I also tried the PVE8.1.3 version, and it was exactly the same as your compilation log, but I checked that there was an error in dmesg.

restart twice

Did you enable SR-IOV in BIOS settings?

[mofakhar]

Yes the Bios entry was already set to enable.
