模块具体型号：jetson-orin-nano-devkit (NX 16GB)
JetPack 6.2
系统启动偶尔会出现[drm:nv_drm_atomic_commit [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x00020000] Flip event timeout on head 0，但是不影响使用，我想了解下这个的报错原因
Hi lishuliang,
Are you using the devkit or custom board for Orin NX?
It seems the error comes from drm driver.
Do you connect any display?
If so, would you hit the similar issue if you remove them?
Please share the full dmesg for further check.
是我们自定义的载板。
我连接了HDMI显示器
这个问题偶尔在出现，在批量生产的机器中，偶尔会有几台机器出现这个问题。

你好，这是dmesg日志
Would you hit this error if HDMI display is disconnected?
Please also share the dmesg in normal case.(w/o seeing the nvidia_drm errors).
HDMI断开的情况下不会出现这种问题
这是正常情况下的dmesg信息

Is it the similar issue as Unable to read EDID for HDMI on AGX Orin - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums?
Have you reviewed for the HW design for HDMI on your custom carrier board?
Have you also tried using another monitor to verify?
1.这是我们批量生产的板卡，同一批次中只有几台出现了这个问题，其他的板卡都没有这个问题。
2.更换过其他显示器还是出现相同的问题。
Are you using DRM application? or you only use xorg with gdm3?
没有使用DRM程序
Then this issue could be ignored. It is just that the callback didn’t return once.
好的，感谢，我还想问一下这个问题出现的原因是什么，可能是什么引起的？
