Check your XIO2001 routing and insure the following for proper IRQ mapping: Slot12: IDSEL A28: socket INTA = XIO2001 INTA Slot13: IDSEL A29: socket INTA = XIO2001 INTB Slot14: IDSEL A30: socket INTA = XIO2001 INTC Slot15: IDSEL A31: socket INTA = XIO2001 INTDAfter crosschecking with our hardware designer the PCB IRQ mapping is the following: J2 : IDSEL A16: => Device 0 : socket INTA = XIO2001 INTA J3 : IDSEL A18: => Device 2 : socket INTA = XIO2001 INTA* **(This should be INTC)* J11: IDSEL A20: => Device 4 : socket INTA = XIO2001 INTA The interrupt routing for J3 is wrong. The XIO2001 driver may expect Device 2 to interrupt on INTC - but it will interrupt on INTA.
What does your interrupt-map property look like then? Note that you have to override both map and map-mask in this case. Arnd
