In late April, the release of Linux 6.3 was marred by a critical error that led to damage in the fire system XFS. The glitch has remained unresolved and is still present in the latest update, 6.3.4. However, the problem is absent in previous kernel branches like 6.2 and a developmental branch of 6.4.
As of now, the cause and specifics of the error are unknown. Therefore, XFS users should avoid updating to the 6.3 branch until the situation is clarified.
