ACPI error, No pointer back to NS node in buffer obj

[Jakub Lach]

Hi, 

I have observed similar errors on amd64 7.1 RELEASE LiveDVD. 

http://forums.freebsd.org/showthread.php?t=1533

These looks T400 specific. 

I'm looking forward to using this machine 
with FreeBSD stable, so I hope these issues will be adressed in current
soon..

All best, 

Jakub Lach
