I saw something similar, and it could be related: when I put a second 
HD in my laptop (using the drive bay) Haiku will show the exact same 
behaviour, obviously, the IDE driver has a severe problems with 
handling interrupts with multiple devices - I guess this happens when 
two devices share the same interrupt. I didn't manage to find the time 
to look into it yet, though.

When I turn off IDE DMA in the boot loader, the system boots without 
any problems (but slow, of course). Does that help you as well?

Bye,
   Axel.
