mkinitcpio Cannot Find ext4?

lsmod indicates ext4 is loaded.

MODULES="ext4"
HOOKS="base udev autodetect sata"

$ sudo mkinitcpio -p kernel26
Password:

Had to copy over kernel26.img from another system. How to resolve the unfound ext4 module (adding filesystems to HOOKS is not the resolution as ext4 is not added)?

Anyone have a clue? Perhaps an issue with the 36 kernel (I have not yet downgraded)?

maybe reinstall the kernel? works for me

modinfo ext4

Should return

/lib/modules/2.6.36-ARCH/kernel/fs/ext4/ext4.ko

If you have this (ext4.ko) file try to run

sudo depmod -a

Deinstalled/reinstalled 36 kernel several times already.

No go there as well. Might have to downgrade to 35 .

Works fine here, too. I would re-download 36 from kernel.org (unless you've done this already). Check the existence of fs/ext4 directory before compiling (although it should most definitely be there).

Also, maybe you should just do [in kernel config before compiling] "CONFIG_EXT4_FS=y" instead of "CONFIG_EXT4_FS=m" and see if that helps. Of course you wouldn't add it to the MODULES section anymore as it would already be present. And for that matter, (I assume you're using the ARCH package from your first post) make sure it doesn't say "CONFIG_EXT4_FS=n" in /usr/src/linux-2.6.36-ARCH/.config after compiling.

Not sure what else, you've probably already done these but who knows..
edit: Also, after you install, try:

pacman -Ql kernel26 | grep -i ext4

and see what it shows.

$ pacman -Ql kernel26 | grep -i ext4
kernel26 /lib/modules/2.6.36-ARCH/kernel/fs/ext4/
kernel26 /lib/modules/2.6.36-ARCH/kernel/fs/ext4/ext4.ko

This particular unresolved issue appears to be related to: https://bugs.archlinux.org/task/21659. However, chroot+ rebuilding initcpio does not resolve the issue.

ERROR: module 'ext4' not found

This error remains persistent above all attempts thus far .
