after install the required packages and enviroments，git clone git://git.proxmox.com/git/pve-kernel.git, and then make.
I can find the 0003-pci-Enable-overrides-for-missing-ACS-capabilities-4..patch file in the pve-kernel/patches/kernel directory ,but after install the kernel , set grub option GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on pcie_acs_override=downstream", restart pve system . The issue about isolate iommu group is still not resolved.
ps: Use the kernel my friend gave me, the group is correct. But I wonder why it is not correct when compiled the kernel by myself. Did I miss any important steps?
