Slackware64-current install in a f2fs partition

After installing onto a f2fs partition (f2fs is offered by the installer), a kernel error happens: unable to find crc32 module.

Seems that neither the default initrd nor vmlinuz-generic has the module and f2fs fails to mount. But if the vmlinuz-huge is used, the system boots fine.

After install I needed to switch to the huge kernel to boot the system.

Are you using lilo?

I am using elilo...

I don't know about elilo, but I do know lilo can't boot a f2fs formatted partition. So, I created a small, 200 meg., /boot partition and formated it with ext4. The / partition (the root partition) and /home are formatted with f2fs.

This system boots from an EFI partition which is FAT based, the thing is, the crc32 module is not included with the generic kerne, which is installed by default on a normal installation, but the f2fs module is. I think it should be included so the generic kernel is able to boot from f2fs partitions. The huge kernel does have the crc32 module built in, and boots correctly.

Have you tried specifying the crc32 module when generating the initrd? If that work,s it might just be that /usr/share/mkinitrd/mkinitrd_command_generator.sh needs to be updated to include that module on some or all installations.
