Hello.

I'm again having the boot failure problem due to commit 68411521 'Reinstate
"crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform
framework"' in linux.git .

---------- dmesg end ----------

In the initramfs, crc-t10dif.ko is included but crct10dif.ko and
crct10dif-pclmul.ko are not included. This is because modules.dep does not
describe that crc-t10dif.ko depends on crct10dif.ko and optionally depends
on crct10dif-pclmul.ko .

I'm using module-init-tools-3.9-21.el6_4 / binutils-2.20.51.0.2-5.36.el6 /
dracut-004-303.el6 / gcc-4.4.7-3.el6 and there is no modules.softdep file.

Did commit 7cb14ba7 "modules: add support for soft module dependencies"
silently introduced dependency on module-init-tools which can generate
modules.softdep file ( module-init-tools >= 3.11 ) ?

Kernel config is at http://I-love.SAKURA.ne.jp/tmp/config-3.12-rc1-modules .

Regards.
