rootdelay has no effect.
The next-to-last message is "waiting for root filesystem", the last message is something about usb...
After that the system hangs.
I tried using sda instead of hda and it works!
Maybe it would be better to use uuid to avoid these problems.
Some time ago I heard about hda to sda rename but I hadn't thought about that ^_^'
Sorry for wasting your time.
