2.1 | 5 | The cause is a stricter check of the default behavior of the Intel IOMMU. This now checks for correct functionality. If this check fails, some components cannot be initialized correctly.

However, as long as you do not intend to virtualize anything on the hardware, this is not a major issue and the function can be disabled. |
