installation failed on esxi 5.1 iommu head/tail error

Hello

I am a new user and i have a motherboard Supermicro H8QI6-F and when i install it gives me iommu head/tail error .

I am trying to figure out what is causing it but do not know the exact cause.Maybe its not resetting the iommu log or something like that, I have a Jpg image attached hopefully someone could tell me what it is exactly so i could let supermicro know as they are trying to help ''

Thanks in advance
