Anybody understand this?

 

I have not been able to get pass through working (sound or video) in a VM - is this call trace related?

 

Thanks

Look for BIOS updates.  Since they're all apparently IOMMU related, and you're not running any VM's with passthrough, you can safely disable IOMMU / VT-D within your BIOS.
