ktest config bisect ended with:

***************************************
Found bad config: CONFIG_PCI_MSI
***************************************

diffconfig good_config bad_config
-ENA_ETHERNET n
-FM10K n
-GENERIC_MSI_IRQ y
-GENERIC_MSI_IRQ_DOMAIN y
-I40EVF n
-INTEL_IOMMU n
-IRQ_REMAP n
-IXGBEVF n
-LIQUIDIO_VF n
-NFP n
-PCIE_DW_PLAT n
-PCI_MSI_IRQ_DOMAIN y
-VMD n
PCI_MSI y -> n


When that is not set, it fails to boot. It boots fine if I enable it.
