> irq1: 12934636 44756 ... > So apparently, something's wrong with the gem driver.. I think the gem driver is OK, but the irq mapping looks very dodgy. Would you be able to drop into OpenFirmware and list the properties of the gmac device and the parent UniN host-pci bridge ? e.g. on my emac: 0 > dev enet 0 > .properties ... (not so important) 0 > pwd /pci@f4000000/ethernet@f 0 > dev .. 0> pwd /pci@f4000000 0> .properties ... interrupts ... interrupt-map interrupt-map-mask These are used by the irq assignment code in ofw/ofw_pci.c, which assigns irqs base on the host bridge's interrupt-map for each device on the bus. It looks like it might be getting things wrong for GEM. To avoid the tedious typing out, it's worthwhile using the OpenFirmware telnet server as described in http://developer.apple.com/technotes/tn/tn2004.html and capturing the output in a terminal window. later, Peter.
