That being said, we might have two options: 1) bisecting the kernel version, 2) trying 5.15 with all the f2fs upstream patches. 1) this requires lots of effort between 5.15 vs. 5.18 tho, is it doable? 2) https://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-stable.git/log/?h=linux-5.15.y Is it doable to test this kernel? If this issue happens with this kernel, we can bisect among f2fs changes easily. -- You may reply to this email to add a comment.
