Hi there!

I also faced this bug on xiaomi mi Router 3g on different HDDs with ext4 filesystem.

I've OpenWrt SNAPSHOT r5629-23bba9c release, which equipped with 4.9.72 kernel.

I haven't seen any kernel log which might be relevant to this problem only when mysql tries to acces some block and it can't read...
