I believe a command sequence like this can be used to reliably reproduce
the issue:

umount /mnt
truncate -s128m /tmp/test.img
cmd="/sbin/mkfs.ext3 -E stride=128,stripe_width=512 -F /tmp/test.img"
echo $cmd > /dev/kmsg
$cmd
mount -o loop /tmp/test.img /mnt/
while dd if=/dev/zero of=/mnt/$RANDOM bs=1M count=1; do true; done

I do not see any failures when ext4 is replaced for ext3 above.
