 # Handle camera service around suspend/resume.
 #
-# v4l2-relayd must be stopped before suspend to avoid GStreamer crashes,
+# On resume the IPU7 firmware re-authenticates (CSE authenticate_run),
-# then restarted after resume once the camera hardware is ready.
+# but the ov08x40 sensor is not re-bound to the media-controller graph.
+# libcamhal then reports "No sensors available", icamerasrc fails to
+# register properties, and /dev/video50 stays empty — the camera looks
+# dead to every app until reboot.
 #
-# The post-resume restart uses systemd-run to avoid blocking the
+# Workaround: after resume, unload + reload ov08x40 and intel_ipu7_isys
-# password prompt while waiting for the camera to initialize.
+# so isys re-probes the sensor via ipu_bridge.
+#
+# DO NOT unload intel_ipu7_isys pre-suspend: s2idle wake requires the
+# IPU7 driver to be attached, and unloading it before suspend hangs the
+# machine on wake.
+#
+# The post-resume work runs via systemd-run so it doesn't block the
+# lock-screen password prompt while modules settle.
