The only other source of hardware caused xruns I know is when I keep the audio media on the same hdd as my ~. Those occasional xruns went away when I started keeping audio files on another hdd used for nothing else.

I came across a script that sets the irq priorities and stops some services and the performance ended up about the same or very similar as a real time kernel.
irq priorities
"rtc" - realtime clock
"ehci_hcd:usb2" - USB port 2
"snd" - internal sound chip
"i8042" - keyboard/mouse/touchpad controller
RTIRQ_NAME_LIST="rtc usb2 snd i8042"
RTIRQ_PRIO_HIGH=90
RTIRQ_PRIO_DECR=10
RTIRQ_PRIO_LOW=51
possible services to stop
network-manager (optional)
resolvconf
pulseaudio
apport
cron
cups-browsed
grub-common
speech-dispatcher
