<pre>Hm, what does the following show?
cat /sys/bus/pci/devices/0000:02:00.0/power/control # GPU
cat /sys/bus/pci/devices/0000:02:00.0/power/runtime_status # GPU
cat /sys/bus/pci/devices/0000:02:00.0/power/runtime_usage # GPU
cat /sys/bus/pci/devices/0000:02:00.0/power/runtime_active_kids # GPU
cat /sys/bus/pci/devices/0000:02:00.1/power/control # HDA
cat /sys/bus/pci/devices/0000:02:00.1/power/runtime_status # HDA
cat /sys/bus/pci/devices/0000:02:00.1/power/runtime_usage # HDA
cat /sys/bus/pci/devices/0000:02:00.1/power/runtime_active_kids # HDA
I can't see anything in dmesg that the HDA controller is bound to a driver.
What does the following show?
ls -l /sys/bus/pci/devices/0000:02:00.1/driver</pre>
