I just had the same problem, enabling the kernel option CONFIG_RANDOM_TRUST_CPU indeed fixed it.

To include MSI support into the kernel requires users to rebuild the kernel with both the configuration parameters CONFIG_PCI_USE_VECTOR and CONFIG_PCI_MSI set. CONFIG_PCI_USE_VECTOR enables the kernel to replace the IRQ-based scheme with VECTOR-based scheme because MSI requires a unique vector and no BIOS interrupt-routing table. CONFIG_PCI_MSI enables MSI support in the kernel.
