Hi, 

I think I've got to the bottom of this.  I suspect that the PC-BSD 9.x 
snapshot was built at an unfortunate time - I suspectyou are suffering 
from a bug that was intriduced into FreeBSD in SVN r215865, and fixed 
the following day, in r216012.  Is there any way you are able to 
verify this?  I'm not a PC-BSD user myself so don't know if you can, but 
if you could apply the change at 
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/i386/i386/machdep.c.diff?r1=1.713;r2=1.714 
and recompile the kernel, then I believe that will fix the problem you 
see. 

I shall try to contact the PC-BSD folk and point this out, hopefully they 
will be able to con firm if the kernel was built with code from between 
those two revisions.  I don't know if there are any plans to release a 
new snapshot, but this bug will be fixed in any future ones.
