Hi Conrad,

thanks for the hint. Do you know which commit may broke the driver? Is
there any patch or workaround?

I do not have access to the physical machine, only full root access to
the guest. I don't want to bother with the cloud provider, I'm happy
that they offer FreeBSD at all as a default installation.
