iMx6ull File-System Corruption issue on "rootfs" Partition during Bootup

Hello Folks,

We are using iMx6ull based custom linux board with below BSP version.

Linux Kernal-Version = 4.19.35

DISTRO_VERSION = "4.19-warrior"

On one of the device, we are facing fs-corruption issue due to which processor could not recover by itself (kernel-panic!) and need some manual intervention to reset it and fix corrupted partition by running e2fs tools.

We have shared an issue log here. Please let us know if this issue has some genuine kernel bug (as it is related with low level JDB2 kthread) and any patch available or can be done to fix it.

This issue is seen on the device with long-run (2 to 4 months). What we are suspecting is that why kernel thread is not recovering corrupted descriptor-block automatically ? (if checksum failed?)

Any help appreciated!

Regards,

Nirav Agrawal
