I have tried to reproduce this using an armv5tel arch (qemu emulation),
running a stock 3.7.3 kernel.  The test image was created on x86_64 with
a stock 3.7.3 kernel, and the test image then booted as the rootfs on the
ARM system.

No corruption of the filesystem occurred on the ARM, even with
parallel file writes/moves to 'encourage' the bug to appear.
The unmounted filesystem checked-out OK on the x86_64 using
xfs_check.

Is there some missing information here or additional actions needed to
trigger this bug?

Thanks

Phillip
