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. -- Sitsofe | http://sucs.org/~sits/ -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
