Hi,

Do you pick up 4.14 kernel from AOSP, or just kernel.org? did you try fsck on
this image?

Hi Chao,

The kernal code was taken from the raspberry pi git repo, and then the
incremental patches applied.

Yes, fsck has been applied. Please see below the output of the both volumes.

Please let me know if you require any more info.

Regards

John

I didn't see any corruption there, does this image still panic your kernel?

Hi Chao,
I’ve applied all incremental patches up to, including 4.14.101. I can also
confirm that my build is a %100 match between the .xz file on kernel.org (
with respect to fs/* ).
Yes , totally repeatable. Actually it appears to panic about 8 times on
reboot.
Also the panic is not kernel version specific as I’ve tried multiple kernel
versions. Same result. I’ve also reformatted a new sdcard, tar’d up all the
data on the old card, and transferred to the new one, and all is fine.
One other separate issue, should the
/sys/fs/f2fs/mmcblkXpY/lifetime_write_kbytes work in 4.14? Mine doesn’t,
but I have seen it work in Ubuntu 18.4 with 4.15 kernel. On reboot values
return to 0.

Hope this helps
John

--- Comment #5 from phiber2000@gmx.de ---
The issue was observed in the kernel version 4.14.98 an is still present in
4.14.106.
We successfully backported a commit of Chao Yu from 4.19 to resolve the issue.
Maybe it should be considered to be done here in the kernel.org upstream, too.

Was fixed with a backported patch ("f2fs: fix to skip verifying block address
for non-regular inode")

Close it.

Maybe my mistake, but I can't find the backported patch in the v4.14.y branch.
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-4.14.y&qt=grep&q=f2fs

Could you just check that?
