+# Workaround for RK3566 DRM VBlank hang on reboot/shutdown (kernel 7.0.2).
+#
+# Root cause: drm_atomic_helper_wait_for_vblanks() has no timeout. It is called
+# from the DRM reboot notifier chain, which runs for both normal reboots and
+# sysrq-b (machine_emergency_restart does NOT bypass the notifier chain on this
+# kernel/platform). If the display is powered off before reboot, hardware vblank
+# interrupts stop and this wait hangs for ~5 minutes until an internal timeout.
+#
+# Fix: do NOT power off the display before rebooting. With the display active
+# and hardware vblanks still occurring, the DRM notifier completes in <100ms.
+#
+# Verified with persistent systemd journal across reboots:
+#   Before fix: shutdown → new boot = ~6 minutes
+#   After fix:  shutdown → new boot = ~17 seconds
+#
+# Device: RG ARC-D (RK3566), ROCKNIX 20260601, kernel 7.0.2

+Documentation=https://github.com/ROCKNIX/distribution/issues/
+# Without this service, drm_atomic_helper_wait_for_vblanks() in the Rockchip
+# DRM driver hangs indefinitely during shutdown (no timeout), blocking the
+# reboot notifier chain and preventing the device from rebooting.
