Well, there is irq/16-snd_hdsp after all once I plug the Cardbus card in
(it's usually out in the morning since the computer doesn't wake up

once I _rerun_ /etc/init.d/rtirq. Otherwise it sticks at the bottom.
Ok, something to keep in mind.

Oh wait. snd_hda_ would be the laptop internal sound card, not the
Hammerfall DSP. The latter doesn't have its own interrupt apparently,
so this would rather be, uh, irq/16-yenta ? That one's at the bottom in
the list. Darn it. I probably removed it when I put the Hammerfall
into storage. And got it out again since the Mackie Onyx mixer is too
bulky for Free Software conference duty.
So maybe I should give the Hammerfall a better chance at working. dak@lola:~$ ps ax k priority -o priority,comm
|grep irq
-91 irq/8-rtc0
-81 irq/17-firewire
-71 irq/32-snd_hda_
[snip]
20 irqbalance
Looks like somebody is prioritizing my soundcards.
Much likely it's Rui's rtirq script. For what ever reason Ubuntu
keeps it in init.d and doesn't start it by a systemd unit.

Instead of ps, you could run
/etc/init.d/rtirq status
I can't speak for your computer, but usually rtc shouldn't be
prioritised anymore and irqbalance should be completely removed.
