Some drivers may accept the remain-on-channel command, but instead of indicating start event for remain-on-channel, just indicate that the operation has been canceled immediately. This could result in continuous loop of search/listen states with very limited time to do anything else in wpa_supplicant if the scan command is also completed quickly (e.g., if the driver is unable to scan other channels than the current operating channel). As a workaround, do not start the next step (search) in P2P device discovery if this type of rejection of listen operation is detected. This gives some more time for wpa_supplicant to handle whatever else may be needed at to be done at the same time and reduces the amount of CPU used in a loop that does not really work correctly from the view point of being discoverable.
