Kernel 6.5.11-4-pve errors in dmesg (seem harmless)

[Coder84619]

These errors seem to be harmless, as vGPU is working with Windows 11. But maybe some code needs a bit of cleanup? Proxmox 8.1.3 on an Intel i5-1240P.

@kinsong I got to the point: cd /usr/src/i915-sriov-dkms-6.5.11-4

and the directory is not found.

[kinsong]

@Coder84619 You need to execute it first in the download directory：
apt install dkms -y
dkms add .
By default, it will be generated in usr/src/

[Coder84619]

I worked through it and now the dmesg logs are clean. Thanks! I did need to make two tweaks:

should be (PKGVER in all caps):

sed -i 's/"@pkgver@"/"6.5.11-4"/g' ~/i915-sriov-dkms/dkms.conf

Otherwise I got:
root@proxmox1:~/i915-sriov-dkms# cat ~/i915-sriov-dkms/dkms.conf
PACKAGE_NAME="i915-sriov-dkms"
PACKAGE_VERSION="@pkgver@"

And reinstall dkms:
apt-get install --reinstall dkms -y

[kinsong]

The comment section will be automatically formatted, just set it to shell now

You may have added "kvmgt" in /etc/modules according to pve's mdev documentation. If using sriov, the "kvmgt" module is unnecessary, just remove it.

** Update: ** The issue is that the machine is using systemd-boot not grub.

@kinsong I used a similar setup but things were not working.
