This also does not go away with the new kernel.

The server exists in a local network, has a private  IP address, and  
is referred to by a short DNS name (which the local name server  
resolves to the private IP address and a non-existent fully qualified  
DNS name). When a share is mounted from the server, and the computer  
is moved to a public network it won't suspend.

When the computer is disconnected from any networks it suspends  
normally.

To reproduce easily just mount a local share (I used an IP alias on  
eth0 to do so, does not work with 127.0.0.1), and set

iptables -P OUTPUT DROP
