I didn't build with --debug=full.  I've been using ALSA as supplied with
linux kernel 2.6.21.1, and built without CONFIG_SND_DEBUG or
CONFIG_SND_DEBUG_DETECT

I have now switched to 2.6.21.6, and turned on both of CONFIG_SND_DEBUG*.
I also uncommented the printk() calls in mce_down(), and moved the first
one down below the definition of the variable 'timeout'.

Here are the kernel messages I got:
