Not when I tested here. Turn off 4K stacks.

Did xfs_repair fix the damage?

XFS on i386 with 4K stacks isn't safe. People are working on making
it better but it's a bit of an uphill battle in some ways.
I've posted patches in the past to change of some the config logic to
avoid this but none of them ever got much more than a grunt ora snarky
anti-XFS comment, it's probably time to do it again.
