That's not true. Later in the comments there is a person without HW raid who also has been affected.

There's nothing indicating that's limited to 6.3.3 exactly. In fact in the same discussion kernel 6.3.1 was reported to having had this issue.

Also, a developer chimed it and said it's probably specific to the entire 6.3.x series because patches for 6.3.1-6.3.4 did not introduce any serious XFS specific changes.
