[SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

When trying out linux 5.11 for its support of the amd sfh I seem to have a problem loading my f2fs root partition.

I found this thread for linux 5.6 where adding a bunch of crc32 related modules to the initramfs seemed to help, but it does not in this case.
https://bbs.archlinux.org/viewtopic.php?id=220607

Using a sysv or systemd based initramfs does not seem to make a difference either. I built linux-mainline directly from the AUR pkgbuild without changes.
Any ideas?

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

Can you find the crc32 module files if you search around in /usr/lib/modules? I tried looking at the config file for the linux-mainline AUR package and the crc32 settings in there seem to look the same as in the normal Arch linux package, so I guess the modules should have been built.

Maybe something with the autodetection hook of mkinitcpio went wrong? Try booting using the "fallback" initramfs instead of the normal one (small) one. You can check the file contents of the initramfs file with "lsinitcpio", see here an example:

$ lsinitcpio /boot/initramfs-linux-lts.img |& grep crc
usr/lib/modules/5.4.89-1-lts/kernel/crc32c_generic.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc32c-intel.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc-itu-t.ko
usr/lib/modules/5.4.89-1-lts/kernel/libcrc32c.ko

$ lsinitcpio /boot/initramfs-linux-lts-fallback.img |& grep crc
usr/lib/modules/5.4.89-1-lts/kernel/crc16.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc32c_generic.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc32c-intel.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc32_generic.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc32-pclmul.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc7.ko
usr/lib/modules/5.4.89-1-lts/kernel/crc8.ko

Those commands produced the following output for me:

usr/lib/modules/5.11.0-rc3-1-mainline/kernel/crc32c_generic.ko

usr/lib/modules/5.11.0-rc3-1-mainline/kernel/libcrc32c.ko

$ lsinitcpio /boot/initramfs-linux-mainline-fallback.img 2>&- | grep crc
usr/lib/modules/5.11.0-rc3-1-mainline/kernel/crc16.ko
usr/lib/modules/5.11.0-rc3-1-mainline/kernel/crc32c_generic.ko

usr/lib/modules/5.11.0-rc3-1-mainline/kernel/crc7.ko
usr/lib/modules/5.11.0-rc3-1-mainline/kernel/crc8.ko
usr/lib/modules/5.11.0-rc3-1-mainline/kernel/crc-itu-t.ko
usr/lib/modules/5.11.0-rc3-1-mainline/kernel/libcrc32c.ko

I needed to modify them a bit because lsinitcpio butched the output for me.

EDIT:
Fallback does not boot either for me, so yeah...

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

In case it helps, these is what I'm currently seeing with linux-mainline.img (non fallback, although it does not make a difference)

My mkinitcpio.conf:

Edit: Added mkinitcpio output

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

I would suggest switching to the none systemd based hooks to unlock the root account in the initrd or copy /usr/lib/initcpio/install/systemd  to /etc/initcpio/install/systemd and change

         echo 'root:*:::::::' >"$BUILDROOT/etc/shadow"

to

     echo "root::::::::" >"$BUILDROOT/etc/shadow"

then rebuild the initrd.  Then you can check what modules are loaded from the emergency shell and try to manually mount the root filesystem.
Are the BPF:No data messages new?

After using the systemd approach and doing lsmod, this is what I got:

Should I test anything else?

I don't know whether the BPF messges are new. They don't show up in dmesg when booted and booting is to fast to see them while in the ram disk

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

Try manually mounting the root filesystem,  I do not use f2fs so I do not know what options you might need to supply beyond the normal device and mount point:

mount /dev/path/to/root/device /new_root

cat /proc/crypto

Are there any entries with name crc32c and type shash?

Yes, the first one is crc32c

name: crc32c
driver: crc32c-generic
module: crc32c_generic
refcnt: 2
[...]

EDIT:
I don't see 'shash' but a couple of different sha's are in there. Here is all output https://imgur.com/a/JAWe5OY

I guess I misread that. But yeah, the first one is 'crc32c' and has type 'shash'

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

name         : crc32c
driver       : crc32c-generic
module       : kernel
priority     : 100
refcnt       : 1
selftest     : passed
internal     : no
type         : shash
blocksize    : 1
digestsize   : 4

This is from a 5.11-rc3 kernel where the crc32c-generic is built in but I do not think that is relevant,  the type line is two up from the bottom and has the value shash.
Edit:
Ah cross post,  well that should match what the f2fs module is trying to load.
Check dmesg for more output?  Try the built linux 5.11-rc3 from Unofficial_user_repositories#miffe.

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

Okay, I've installed the precompiled package which did not seem to change much (anything), but dmesg's output seems interesting enough ...
https://i.imgur.com/rZjLDgq.jpg

What happened at 54s in is the result of trying to mount manually

Edit:
This seems kinda related: https://bugs.launchpad.net/ubuntu/+sour … ug/1911359

So yeah this seems to be a bug, maybe. Weird that it slipped through until rc3 though.

Edit2:
This is probably hw-related as I too am using a Renoir based laptop.

I can't tell if this should be reported somewhere else or if it is already sufficiently taken care of by the ubuntu folks.

Re: [SOLVED] linux 5.11-rc3: f2fs cannot load crc32 driver

Okay that seems to have done it, it's up and running now (but without amd sfh, seems that isn't built by default - should've thought of that...)

Thanks you loqs for helping uncover this.
