This is the kernel bug tracker. What's the kernel bug here? From the log above it's unclear what lead to these corruptions. There should be messages preceding the above, maybe something is wrong with the underlying disk device. According to the message one should "unmount and run xfs_repair" -- did you try that?[0]. Did it help? For further assistance, maybe the mailing list[1] can be consulted, but the folks over there will possibly need more details also: which kernel version, what kind of file system setup, what happened before these errors, etc. [0] Be sure to do have a (block level) backup before running xfs_repair.

Agreed, this is simply a report of corruption, and there is not nearly enough information to act on or triage.
