My system is on one dual path SAN volume (sda,sdb). With 0.4.8-r1 sda1  
(/boot), sda2 (swap) and sda3 (/) are correctly mapped so I can boot.  
But sda5 (/usr) and sda6 (/var) are not mapped... Mapping breaks at  
sda4. So I don't have access to all I need (as /usr/lib for libaio,  
parted, ...). Instead sda4 is mapped which doesn't contain any  
filesystem (base extended partition).

If you cannot get access to a SAN I will see if I have time to do a  
setup at work.
