Does this happen only on first boot? If it happens on every boot, try doing "service kldxref start", then see if it's better on the next boot. My theory is that the root problem here is that kldxref can't be run as a cross-tool. So on first boot, module dependencies don't get handled correctly. But kldxref should run automatically on the first boot and then things should be right after that. We *really* need to fix kldxref to be runnable as a cross-tool. -- Ian
