HQ Camera: stop_streaming: Timeout waiting for buffers to be returned - 2 outstanding, videocore firmware hangs

Describe the bug I'm using GStreamer to get 720p25 input from the official HQ Camera, then the video is processed and finally encoded with omxh264enc. Stopping the stream sometimes causes the kernel message "stop_streaming: Timeout waiting for buffers to be returned - 2 outstanding" together with a backtrace. Subsequent stops/starts of the stream cause similar backtraces with a growing number of outstanding buffers. Eventually the GStreamer process will hang in "Ds" state and three kworker/events processes will hang in "D" state. Unmodified Linux kernel 5.10.17-v7l+ from Raspberry Pi OS. GStreamer 1.14.4 from Raspberry Pi OS.

To reproduce Attach a Raspberry Pi HQ Camera to a Pi 4B. Run latest Raspberry Pi OS. Use the following GStreamer pipe:

v4l2src name=videosrc ! video/x-raw,width=1280,height=720,framerate=25/1 ! queue ! videorate max-rate=25 ! queue ! glupload ! glcolorconvert ! gloverlay overlay-width=1280 overlay-height=720  name=imageOverlay alpha=0 location=web/overlayImg/test.png ! glcolorconvert ! gldownload ! queue ! textoverlay valignment=bottom halignment=center line-alignment=left font-desc="Sans, 28" name=txt shaded-background=yes ! tee name=videoUncompressed ! omxh264enc target-bitrate=1500000 control-rate=variable periodicity-idr=100 name=encoder ! video/x-h264,profile=high  ! tee name=vid ! queue name=rtmpsink_start ! h264parse ! queue ! flvmux name=mux streamable=true
alsasrc name=audiosrc ! queue ! audioresample ! audio/x-raw,rate=48000 ! volume volume=1.8 name=volume !  queue ! tee name=audio ! queue ! voaacenc bitrate=128000 ! queue ! mux.
mux. ! queue2 name=sinkQueue ! rtmpsink name=rtmpsink
vid. ! queue  name=udpsink_start ! rtph264pay ! udpsink host=127.0.0.1 port=8004 name=udpsink
audio. ! queue ! opusenc bitrate=48000 ! rtpopuspay ! udpsink host=127.0.0.1 port=8005 name=udpsink_audio
videoUncompressed. ! queue ! videoconvert ! kmssink

Video source is /dev/video0 (Pi HQ Camera), audio source is hw:2 (USB audio device), these are set from python code starting the GStreamer pipeline.

Expected behaviour No hang.

Actual behaviour Stopping and restarting the stream caused the following error messages: stop_streaming: Timeout waiting for buffers to be returned - <N> outstanding with N (integer) strictly monotonically increasing each time the stream was restarted. This time the sequence for N was 2 8 13 18 23 28. After that, a backtrace is logged. After the backtrace, there is a varying number of messages videobuf2_common: driver bug: stop_streaming operation is leaving buf <addr> in active state with addr being a 32 bit value varying each time.
