Hi,

https://packages.ubuntu.com/trusty-updates/linux-lowlatency is only
available for amd64 and i386 architecture, so ensure that you boot a
default kernel with "threadirqs".

I don't now how to edit the config for the config of GRUB2, but for
syslinux the one and only config would look similar to

[rocketmouse at archlinux ~]$ grep "LABEL Threadirqs" -A4 /boot/syslinux/syslinux.cfg
LABEL Threadirqs
    MENU LABEL Arch Linux ^threadirqs
    LINUX ../vmlinuz-linux
    APPEND root=LABEL=archlinux ro threadirqs
    INITRD ../initramfs-linux.img

Install https://packages.ubuntu.com/trusty/rtirq-init and edit
 /etc/default/rtirq .

Reboot and run

  /etc/init.d/rtirq status

this might show if additional tuning might help, e.g. unbinding devices.

Regards,
Ralf
