Public bug reported: In newer Ubuntu 18.04 HWE kernels, it is possible for GPU HDA controllers to be dynamically runtime-suspended if the HDA's power/control mode is set to "auto". However, pm-utils explicitly sets this to "on" when resuming, which prevents runtime power management of these devices from working as intended.
