Hmm... ICH7.  I recently had a different bug report on < ICH7 (don't 
remember whether it was 4, 5 or 6).  In that case, the drive went 
completely offline after resume.  It never came back after retries.  It 
seemed like the device needed hardreset after waking up from sleep which 
we currently only support for >= ICH8).

Mark, you played with the hardreset bits in PCS (right?) register.  What 
do you think about adding it?  Last time I played with it, the presence 
detection seemed unreliable so hotplug might not work too well but as 
long as the hardreset itself works we can augment it with follow up srst 
for cases like this.

What happens if you stop the playing and restart it?  Does it play okay?
