Hmm, sorry, my mistake here, I fixed a problem on xfs_readlink, not at xfs_symlink.

Although, by your last screenshots, it doesn't look to be related with the problem
I was working before.

On all screenshots the system is crashing while trying to acquire a mutex lock, I don't
know much about the code path where the crash is happening, but, maybe if you enable
CONFIG_XFS_DEBUG we can get some extra hints about where the system is crashing? Also,
have you fsck'ed this FS? maybe an `xfs_repair -nv` would give any clue if there is any
corrupted metadata which would cause this error
