Are you using an initrd? The b43 driver tries to load the firmware when it is initialised. If b43 is builtin (not a module) then the load will happen at boot time - when the initrd is mounted, but before the real root - and the firmware won't be found. The solution is to either copy the firmware to the initrd, or build b43 as a module and make sure the module isn't on the initrd. > CONFIG_FIRMWARE_IN_KERNEL=y Trying to include the firmware blobs in to the kernel binary is unlikely to work for b43, because b43/main.c only defines 7 firmware files in MODULE_FIRMWARE(). There are ~117 firmware files in /lib/firmware/b43 and your wifi card requires some subset of those, probably not the 7 that are defined. _______________________________________________ b43-dev mailing list b43-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/b43-dev
