[SOLVED] Custom kernel: load modules.dep; request for firmware failed.

I installed a custom with the ABS kernel26 package (kernel version suffix -max), but I get errors during boot:

...
NET: Registered protocol family 33
modprobe: FATAL: Could not load /lib/modules/2.6.35-max/modules.dep: No such file or directory

modprobe: FATAL: Could not load /lib/modules/2.6.35-max/modules.dep: No such file or directory
...
:: Running hook [udev]
:: Triggering uvents...iwlagn 000:02:00.0: request for firmware file 'iwlwifi-5000-2.ucode' failed.
000:02:00.0: request for firmware file 'iwlwifi-5000-2.ucode' failed.
000:02:00.0: no suitable firmware found!

The system starts up fine, but my wireless intel card is not detected.

However when I boot without the mkinitcpio ramdisk, the error messages do not appear and my wireless card is recognized properly.


Thanks a lot.

Make sure to also build the headers.  The PKGBUILD should have:
pkgname=('kernel26-max' 'kernel26-max-headers')

And rename the default build functions to
package_kernel26-max() {
...
package_kernel26-max-headers() {

slytux, I followed the guide https://wiki.archlinux.org/index.php/Ke … 26_Package and already did that.

Thanks.

Add the firmware file to your initcpio if you are going to try and load it before root is mounted.

Re: [SOLVED] Custom kernel: load modules.dep; request for firmware failed.

Thanks a lot falconindy, that worked.

Here's what I did specifically.
I made my initcpio ramdisk include both the modules.dep and iwlwifi-500-2.ucode files by modifying /etc/mkinitcpio.conf:

FILES="/lib/modules/`uname -r`/modules.dep /lib/firmware/iwlwifi-5000-2.ucode"

Only this always includes modules.dep of the currently running kernel (uname -r) into the ramdisk. So be careful when building a ramdisk for a kernel configuration different from the one currently running.
(Or maybe there is a better way to get at the name of the target kernel within mkinitcpio.conf?)

unnecessary. mkinitcpio adds depmod files to the image for you. You can examine the contents of the generated initcpio with:

bsdtar tf /boot/kernel26.img | less

or whatever the name of the boot image is...

I forgot to mention I compile almost everything directly into my custom kernel and don't need any modules loaded at boot. So MODULES is empty in /etc/mkinitcpio.conf, and modules.dep does not get added. If I add a module there I don't really need at boot time, e.g.

MODULES="nvidia"

then modules.dep gets added.

That's probably easier and safer than including modules.dep manually...
