It seems that it doesn't find the firmware to load. There are two things I found: 1) it seems it searches paths in kern.module_path, which by default is /boot/kernel;boot/modules. But I had my firmware installed in /boot/firmware. 2) it seems that modules that load a firmware blob are linked to this in the linker.hints file which must also reside in module_path I suppose. Getting the kernel modules, seems to require net/iwi-firmware-kmod, but this does not install the firmware, it install kernel modules and the linker.hints, although the firmware is distributed with the source. The linker.hints file seems to be defined in the makefiles for each kernel module, ie. in iwi_bss/Makefile you have: KMOD= iwi_bss FIRMWS= iwi_bss.fw:iwi_bss:300 .include <bsd.kmod.mk> Getting the firmware seems to require net/iwi-firmware which installs the firmware in /boot/firmware, but it seems further that filenames does not match those in the hints file, instead of iwi_bss.fw it installs iwi-bss.fw So things don't match up. A possible solution should then be: set kern.modules_path to include /boot/firmware or copy the firmware to /boot/modules. Make sure to link firmware files to the filename in linker.hints. That is replace '-' with '_'. I haven't had success with this yet - but maybe I've been messing too much around now, need a break. There is some development, I'm not sure if it has been imported into the source tree yet, http://people.freebsd.org/~mlaier/new_iwi/ There are two files of interest: 20060315.both.tgz 20060418.both_nofw.tgz The former includes the firmware and seems to let you create the linker.hints by editing the Makefiles, but beware that the firmware is installed under yet new names. The second is AFAIK the latest kernel modules. Has anyone succeeded in getting this to the end and get iwi firmware to load?
