This seemed to be worthy of early note:

xfs/031 30s ...[  587.843478] XFS (sdb6): Version 5 superblock detected. 
This kernel has EXPERIMENTAL support enabled!
[  587.843478] Use of these features in this kernel is at your own risk!
*** Error in `/sbin/mkfs.xfs': malloc(): smallbin double linked list 
corrupted: 0x0907f7d0 ***

The test doesn't seem to finish, but Ctrl-c ends the test cleanly.  No 
dmesg stuff is added, and strace doesn't show anything between the mount 
message and the error message.  I'll need to re-enable tracers to 
provide a trace...and as traces can be huge, I'll wait on your advice.

[BTW, the "30s" reference time is from the non-CRC run of your patched 
xfsprogs.  The non-CRC run looked good.]

Thanks!
