We absolutely do load the drivers. Initially, I observed cases where
drivers are missing, but doing more testing with the necessary drivers
present, I still see such messages. A lot of our test infrastructure is
set up to use NFS for mounting to the rootfs and so I am wondering if
that can also be a factor?

Again the drivers get loaded, so that shouldn't be the case.
