It passes on different configurations. e.g. it passes on my single
CPU VM with a 4k block size, but fails with 1k block size on the
same VM. It fails witha 4k block size on a 4 CPU VM but passes with
a 512 byte block size...
It's a race condition somewhere, because adding debug makes it stop
failing. So it doesn't always fail, and it doesn't fail reliably,
either, which makes all attempts i've made to find it go nowhere.

It's an unexpected abort from the libxfs code from verifier detected
corruption. There's a few of these, and I'm slowly working my way
through them (e.g. the last patch in the lastest series).

The problem is that the 32 bit project ID bit is being set by
default now, resulting in the sb_features2 field having a value set
mkfs now needs to be explicit to use 16 bit project IDs, and a
modified form of this patch needs to be added as well:
I need to update that patch and resend it. I get this when I run
with a current mkfs with CRCs enabled:
xfs/187 0s ... [not run] attr v1 not supported

Well, it needs the same mkfs treatment to specifically use 16 bit
project IDs so that it still works on old kernels. And it needs the
_requires_projid16bit() from the above patch, too.

xfs/206 has it's own mkfs filter:
I asked that the generic mkfs filters also be modified to support
ftype, and there hasn't been any followup since then.

Long standing problem with xfs_restore and the way it restores
attributes. The test was written without a fix having been made.
