mountroot prompt after hint.apic.0.disabled=1

[Robert Fitzpatrick]

Don't know if that loader.conf change affected this server, I disabled 
APIC in loader.conf after finding it may be responsible for a slow clock 
on this VMware guest FreeBSD install. I rebooted for the changes to take 
affect and it goes now to a mountroot prompt, can't seem to load the 
root partition. I type ? at the prompt and it does not list anything 
after 'List of GEOM managed disk devices'. Can anyone suggest how I can 
fix this problem?

Thanks, Robert
