Hello,
I'm trying 6.2-rc8 on my Orange Pi PC and noticed this bug in dmesg and
locked-up fsync. (impossible to write to the filesystem)
This just happened after first reboot from v6.1.11.

I had to cut power to shutdown the SBC. Afterwards I did run fsck.f2fs
on the uSD card from my PC which did not reveal any errors.

[FSCK] next block offset is free [Ok..]
[FSCK] fixing SIT types
[FSCK] other corrupted bugs [Ok..]
Done: 0.000000 secs
After next reboot, I got further weird errors (corrupted files,
invalid ELF headers on one .so file, etc.):
https://megous.com/dl/tmp/d409787d4dcb366a.png
Rebooting back to 6.1 fixes the errors and zle.so that had invalid
ELF header is again readable, and zsh works fine:
root@l1[zsh/5.9/zsh] ldd zle.so OK #
linux-vdso.so.1 (0xbeef9000)
libncursesw.so.6 => /usr/lib/libncursesw.so.6 (0xb6e60000)
libc.so.6 => /usr/lib/libc.so.6 (0xb6cc0000)
/usr/lib/ld-linux-armhf.so.3 (0xb6f27000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb6c90000)
Other filesystems (I have linux kernel on VFAT /boot partition seem
to work fine). I can update the kernel on VFAT partition and just reboot,
and it correctly reflects the changes and doesn't lock up.
The particular f2fs_bug_on itself seems to be a new thing in
6.2 https://megous.com/dl/tmp/d7b48ff75a19f285.png
This is a 32bit system.
Any ideas or suggestions?
kind regards,
o.

A bit of followup... I've tried the same kernel on another 32bit system, and
also on a 64bit system, and this seems specific to 32bit systems (happens
on almost every boot). I've run -rc8 and earlier on several 64bit systems
for many days without issues, but the same kernel bugs out on 32bit systems
very early during boot.
Here is more debugging output that can be helpful:

Hi,
I think this should fix the issue. By any chance, could you give it a try?
https://patchwork.kernel.org/project/f2fs/patch/20230307151408.58490-1-chao@kernel.org/
Thanks,
