Yes, this one should be reserved for the timer exclusively AFAIK.

Which ALSA version does your kernel use? (cat /proc/asound/version)
We had some problems with hdspm.c on 2.6.3x kernels as there was much
work going on on the driver, maybe hdsp.c changed as well around that
time.
You should try to compile the newest stable release from
alsa-project.org and see if this fixes things for you.
If not, simply replace hdsp.c with the latest devel version from [1],
rebuild and see, if this works. (unfortunately down ATM)

Andre
