** Description changed: I'd like to reduce clutter and get the most use out of my existing infrastructure so I wanted to stop using an external VOIP gateway for my PSTN lines and use a dedicated card with Asterisk instead via VT-d and the iommu under Virtualbox 4.1.34. The hardware I have is capable and the relevant BIOS and kernel options are enabled. I have set intel_iommu=on and I have also tried using the additional kernel option iommu=pt. After testing I can confirm that this works correctly using linux 3.2.0-70-generic but not with 3.5.0-54-generic, 3.13.0-37-generic or - 3.16.6-031606-generic (from mainline kernel-ppa). I have updated - everything I am comfortable updating including the BIOS but do not want - to push my luck. I noted that there may be a possible solution in + 3.16.6-031606-generic (from mainline kernel-ppa). I noted that there may + be a possible solution in https://bugzilla.kernel.org/show_bug.cgi?id=44881#c49 but that this would not be backported.

Wildcard TDM410 4-port analog card (rev 11) I have setup pci-stub with the above and set vboxpci to softdep on it. Not sure if that's necessary or not as there are no host drivers available. The error I'm seeing when loading the kernel module in the guest (except when using kernel 3.2 which works properly). Modprobe hangs in the guest and eventually causes the guest to freeze. - Oct 24 09:05:08 VMS001 kernel: [ 81.496003] dmar: DRHD: handling fault status reg 3 - Oct 24 09:05:08 VMS001 kernel: [ 81.496032] dmar: DMAR:[DMA Read] Request device [03:00.0] fault addr 7349c000 - Oct 24 09:05:08 VMS001 kernel: [ 81.496032] DMAR:[fault reason 06] PTE Read access is not set + Oct 24 09:05:08 kernel: [ 81.496003] dmar: DRHD: handling fault status reg 3 + Oct 24 09:05:08 kernel: [ 81.496032] dmar: DMAR:[DMA Read] Request device [03:00.0] fault addr 7349c000 + Oct 24 09:05:08 kernel: [ 81.496032] DMAR:[fault reason 06] PTE Read access is not set Another error which may be related...

I'm going to look and see if there is a kernel available to try but I'm not sure if 3.16.6 has it or not.
