--- Comment #11 from Billy <georgewilliamfoster@gmail.com> ---
Can we change the Importance of this bug from "Affects Only Me" to something
higher?  Just to reflect the fact that this bug makes it impossible in install
FreeBSD 13 from the install CD ISO on several major cloud providers like Vultr.

Further, has anyone found a workaround for this?  I know that
devmatch_blacklist can be used if you have access to an existing install.  But
if you're using the install CD, I haven't found a way to prevent
virtio_random.ko from autoloading.  I tried single user.  I tried to use the
"disable-module" command on the loader prompt.  None of that worked, so I am
kind of out of ideas.
