This is the second time I'm seeing this. Note that on linuxbios, the 
message is :
PCI_IDE: not 100% native mode: will probe irqs later

that's different from phoenix. So there is a chipset setting here that 
is wrong. I think there is an IRQ issue here. Note that on the phoenix 
it is irq 5, and on linuxbios it assumes IRQ 14, since it is not a 
native controller (or so linux thinks).

What system is this on?
