Description Oliver Hildebrandt 2018-09-13 07:51:48 UTC

When i boot the Kernel with Message Signaled Interrupts (MSI and MSI-X) activated (What automatically happen when i select IOMMU Drivers) the Kernel won't boot, it hang short before the end of the boot Process.

Here is a Screenshot:

When i disable IOMMU and then disable Message Signaled Interrupts (MSI and MSI-X) it boots.

Kernels older than 4.16-rc1, boots normaly with the Options enabled (4.15.18, 4.14.69).
