0x0b = CS4231_TEST_INIT, and 0x20 = CS4231_CALIB_IN_PROGRESS. At least, mce_down() should show messages if the calibration gets timeout. Did you see any related messages? Or didn't you build with --with-debug=full?
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:
