Some device is floating the IRQ12 line during probing,
tricking the IDE driver into thinking that IRQ12 belongs to ide0.
If you are not using the PS2 mouse input on your motherboard,
then disable it (jumper or BIOS setting) to cure the problem.
Otherwise, use boot parameters to force the correct IRQ (IRQ14).
