Hi, Checking the news (eselect news read), I see that an upgrade to udev-217 might break firmware loading, so the news tagged "2014-11-07-udev-upgrade" says that a kernel >= 3.7 should be configured to: CONFIG_FW_LOADER_USER_HELPER=n Is it that simple? Trying a new kernel build using "menuconfig", it says that CONFIG_FW_LOADER_USER_HELPER depends on CONFIG_FW_LOADER, and this one depends on a huge list of other configuration elements. Any thoughts? Thanks, Francisco
