The SROM reads aren't failing, think out of the box, the more likely problem is: 3) Sun doesn't initialize the SROM for the onboard network devices. You have to obtain the MAC address and other settings by fetching them from the openfirmware device properties. So use something like: #ifdef CONFIG_OF struct device_node *dp = pci_device_to_OF_node(pdev); const char *addr; addr = of_get_property(dp, "local-mac-address", NULL); if (addr) { memcpy(dev->dev_addr, addr, ETH_ALEN); return 1; } return 0; #endif - To unsubscribe from this list: send the line "unsubscribe ultralinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
