Hi Joseph, Can you attach the 3.8.0-32-generic config (the one matching the successful boot at https://launchpadlibrarian.net/156685076/BootDmesg.txt) to the bug? The only way I can match up the output: EISA: Probing bus 0 at eisa.0 Cannot allocate resource for EISA slot 1 Cannot allocate resource for EISA slot 2 Cannot allocate resource for EISA slot 4 Cannot allocate resource for EISA slot 5 EISA: Detected 0 cards. with the code is if we have root->force_probe set, and the only way I see for that to happen is if we're in the virtual_eisa_root_init() path and CONFIG_EISA_VLB_PRIMING=y: #if defined(CONFIG_ALPHA_JENSEN) || defined(CONFIG_EISA_VLB_PRIMING) #define EISA_FORCE_PROBE_DEFAULT 1 #else #define EISA_FORCE_PROBE_DEFAULT 0 #endif static int force_probe = EISA_FORCE_PROBE_DEFAULT; virtual_eisa_root_init eisa_bus_root.force_probe = force_probe eisa_root_register(&eisa_bus_root) eisa_probe(root) printk("EISA: Probing bus %d at %s") if (eisa_request_resources) printk("EISA: Cannot allocate resource for mainboard") # we don't see this if (eisa_init_device) eisa_release_resources kfree if (!root->force_probe) return -ENODEV goto force_probe printk("EISA: Mainboard %s detected") # we don't see this force_probe: for (i = 1; ...; i++) if (eisa_request_resources(i)) printk("Cannot allocate resource for EISA slot %d", i) printk("EISA: Detected %d cards") Bjorn -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
