Hi,

since the IOMMU grouping problems keep me from passing through my GPU, I wanted to ask if I could downgrade my current Proxmox 4.1 (on Debian Jessie) to Proxmox 3 with kernel 3.10.

Or could I even use kernel 3.10 with Proxmox 4??

And yes, pcie_acs_override=downstream is enabled, but doesn't fix the problem.
