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
