Hi DraconPern
That's the weird thing. If I boot my "old" disks which doesn't recognize the raid volume it works, if I remove the disk, replace them with new ones (completely wiped according to ubuntu), the system boots, but doesn't get an IP address, still using the same usb stick. I've also tried different loaders from jun (1.02b, 1.03, 104) with various DSes (3617, 3615, 916, 918+), all of them don't get an IP. Also I've tried different USB Sticks from different vendors (also changing the IDs in grub.cfg) to no avail...
