Assuming your hardware isn't buggy you've tickled a bug in the kernel
rather than a bug in fio so this isn't the right list of your issue.
Since you're running an Ubuntu kernel you need to report it to Ubuntu
(e.g. via https://bugs.launchpad.net/ubuntu/+source/linux/+filebug )
unless you can also reproduce it on the latest mainline kernel from
kernel.org (4.7-rc5 at the time of writing) in which case you would
better off reporting on the Linux Kernel Mailing List / the kernel.org
Bugzilla.
