You get .config:1181:warning: PCMCIA_LOAD_CIS selects FW_LOADER which fails its dependencies! So you then go into `make menuconfig' and type /^fw_loader$ to display FW_LOADER's dependencies. Depends on: HOTPLUG && EMBEDDED then do `egrep "HOTPLUG|EMBEDDED" .config' And we discover weird things. Why does FW_LOADER depend on EMBEDDED? And why the heck does INPUT depend on EMBEDDED?!??! And what's up with CONFIG_SERIO? Depends on: !S390 && (EMBEDDED || !X86) hm. -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
