Well, this looks like the driver is having a problem.
Takashi, have we done any PM changes to that driver recently?
Boris, please send the output of "lspci -vvv' from that box.

So the audio is a Root Complex Integrated Endpoind and there shouldn't be
any problems with it related to PCIe ports power management.
It looks like azx_runtime_suspend() is new in 3.7 and it returns -EAGAIN
to indicate that it actually can't be suspended (if my understanding the
code is correct). However, it shouldn't do that, because that causes
the runtime PM core to repeat the attempts. It rather should implement
a .runtime_idle() callback returning an error code instead.
Those messages are just noise, though.
Thanks,
Rafael

Borislav, could you test the patch below?

Subject: [PATCH] ALSA: hda - Move runtime PM check to runtime_idle callback
The runtime_idle callback is the right place to check the suspend
capability, but currently we do it wrongly in the runtime_suspend
callback. This leads to a kernel error message like:
pci_pm_runtime_suspend(): azx_runtime_suspend+0x0/0x50 [snd_hda_intel] returns -11
and the runtime PM core would even repeat the attempts.

Thanks for quick testing!
I queued the patch for 3.8 kernel now.

Hi Boris and Rafael,
I remember I didn't observed repetitive attempts to suspend if the azx_runtime_suspend() returns -EAGAIN.
Because the HD-A driver does not implement the runtime idle callback, pci_pm_runtime_idle() will call pm_runtime_suspend(dev),
and then __pm_runtime_suspend(dev, 0) will be called.
Finally the code will go to 'fail' of rpm_suspend:
...
fail:
__update_runtime_status(dev, RPM_ACTIVE);
dev->power.deferred_resume = false;
wake_up_all(&dev->power.wait_queue);
if (retval == -EAGAIN || retval == -EBUSY) {
dev->power.runtime_error = 0;
...
if ((rpmflags & RPM_AUTO) &&
pm_runtime_autosuspend_expiration(dev) != 0) ... but since the rpmflags is 0, the code will not go to 'repeat' but to 'out'.
goto repeat;
} else {
pm_runtime_cancel_pending(dev);
}
goto out;
Please correct me if I misunderstand something.
Thanks
Mengdong
