Actually, that looks more like what I'm (still) getting with my old
Layla20 on an ASUS Striker Extreme motherboard:

If I remove the firmware, I get this instead:

So, I think we're looking at a different problem here. It seems like
the interrupts aren't going through for some reason. Why, and is
there anything one can do about it, short of trying a different
motherboard?

uname -a:
Linux localhost 2.6.27-gentoo #2 SMP PREEMPT Fri Oct 17 03:23:28 CEST
2008 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel
GNU/Linux

Using the ALSA drivers that come with the kernel. IRQ 16 is also used
by a Silicon Image SATA interface (sata_sil24), and two nVidia 8800GT
video cards, and there doesn't seem to be much I can do about that.

There are two PCI slots, but one is blocked by a video card cooler. I
could try removing the offending video card and see if the Layla DSP
card works in that PCI slot... Wouldn't really solve my problem
(there are two video cards for a reason :-), but it might be
interesting to see if it has any effect.
