<pre>Okay the HDA's runtime ref counter is 0 and it has no active children, so it
should suspend. Chances are it doesn't because rpm_idle() fails for some
reason.
Could you try this debug patch that I had created for #106597 and post the
dmesg output?

You can add "log_buf_len=10M ignore_loglevel" to the command line to ensure
that dmesg isn't truncated and contains all debug output.</pre>
