Hi Nir,
The wct4xxxp is in a different IRQ than ide0 and ide1 but the issue
is that you have enabled the APIC (which extends the IRQ table). In
reality the card might share IRQ with another device. My advice is
to disable APIC and then check again what IRQ the card gets. If you
see that the card shares an IRQ with another device try if its
possible to disable this device , for example USB.
