[SOLVED] P10S-I - Updating BIOS breaks GPU passthrough

Hi,

it looks like a bug in the iommu group. So the PCIe is not turnoff correctly.
I would if I can flash the old bios and use intel microcode to update the CPU microcode.
 
Hello,

There is a new BIOS 4602 that solve the problem, GPU passthrough works again.

Thanks you for answers wolfgang.
