ext2 can't mount partitions containing files with Japanese characters in their names

[KapiX]

I have copied a few files with Japanese names to ext4 partition that worked fine before. Now even after removing them I get "Bad data" while trying to mount the volume.

I don't think the partition itself has any issues, because Linux doesn't complain about anything.

Nothing in syslog?

Checksum verification indeed failed for this inode. Please post the output of "tune2fs -l /dev/... " with cmd:tune2fs installed.
