What I can tell so far, after trying to put quite a few printk here and there, is that prom.c:psycho_irq_build() doesnt't get called for devices directly hanging off the psycho controler. That's because of_device.c:apply_interrupt_map() can't match the requested interrupt into the interrupt map, and returns NULL. Now, the logic inside apply_interrupt_map() is beyond my understanding of OF. For reference (and debugging), I'm including both interrupt-map and interrupt-map-mask, just in case it might be usefull. root@positive:/proc/openprom/pci@1f,4000# cat interrupt-map 00000800.00000000.00000000.00000002.f006d1b0.00000021.00001000.00000000.00000000.00000001.f006d1b0.00000010.00001000.00000000.00000000.00000002.f006d1b0.00000011.00001000.00000000.00000000.00000003.f006d1b0.00000012.00001000.00000000.00000000.00000004.f006d1b0.00000013.00001800.00000000.00000000.00000001.f006d1b0.00000020.00001900.00000000.00000000.00000001.f006d1b0.00000026.00002000.00000000.00000000.00000001.f006d1b0.00000018.00002000.00000000.00000000.00000002.f006d1b0.00000019.00002000.00000000.00000000.00000003.f006d1b0.0000001a.00002000.00000000.00000000.00000004.f006d1b0.0000001b.00002800.00000000.00000000.00000001.f006d1b0.0000001c.00002800.00000000.00000000.00000002.f006d1b0.0000001d.00002800.00000000.00000000.00000003.f006d1b0.0000001e.00002800.00000000.00000000.00000004.f006d1b0.0000001f root@positive:/proc/openprom/pci@1f,4000# cat interrupt-map-mask 00fff800.00000000.00000000.00000007 As usual, I'll be happy to test any idea you may have to solve this problem.
