Your one liner seems to fix things - thank you! Also discovered I can work around by writing 0 to /sys/devices/pci/<blah>/msi_bus, which will at least mean I can run unpatched Ubuntu kernels until we figure this out :)
Anybody still having problems and wanting to test if this is their issue is welcome to try the kernels I built:
