MODULE_SOFTDEP for crc32c is not working

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1786713

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

there are no logs.

Can you expand upon why it is not working? Was it once working and now it is not? Are you seeing specific errors?

I don't know, why this is not working.
With kernel source 4.15.17 there was no problem.
I didn't see errors while compiling 4.15.18.

btw making initramfs is the problem, not the kernel itself.

@Tim-

Its still not clear exactly what problem you're having. The version numbers you referenced in comment #5 suggest that you're compiling your own kernel from the 4.15.x mainline stable source (but the reference to "4.17.18" in the bug description confused me; was that a typo?).

Given your mentions of MODULE_SOFTDEP, crc32c, and 4.15.18, my guess is that perhaps you need to apply this patch to your repo:

    ext4: add MODULE_SOFTDEP to ensure crc32c is included in the initramfs
    https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/bionic/commit/?h=master-next&id=f1374d4425d95f4b26637525cb5a776994ce8042

Note that we have that patch pending for release in Ubuntu Bionic's kernel, but if you're building your own from the mainline stable v4.15.18 source, you'll need to apply it to your own repo.

If that doesn't resolve your issue, please describe the problem more explicitly, including the exact commands you're issuing and the specific error message that results.

ohh sorry, 4.15.18
