Hello,
We are using L4.1.15 as reference for our custom board linux.
After 2-3 days of power-cut aging test, the UBIFS error occurs and system hangs up at boot.
UBIFS error (ubi0:0 pid 1): replay_log_leb: bad sqnum 257093, commit sqnum 257458

No filesystem could mount root, tried: ubifs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
After upgrade nand driver to 4.9.123 the problem seems to be suppressed.
What is the root cause of the error? Is upgrading kernel/driver the only way to solve this issue?
