请问J6域控接收相机视频失败dmesg中遇到FCHM Int occur (14, 38, 127326)错误是啥原因？

我们有个J6域控接收isx031这个相机视频，硬件连接：isx031(MAX96717加串器)---GMSL2--->J6域控（MAX96722解串器）---MIPI--->J6域控（SoC），这种简单情况是正常的，dmesg关键log也可以看到第一帧FS/FE正常接受，如下：

由于业务需要，我们需要在isx031和J6域控之间加一个GMSL2中继器（MAX96724解串器+MAX96717加串器），硬件连接：isx031(MAX96717加串器)---GMSL2--->GMSL2中继器（MAX96724解串器）---MIPI DPHY--->GMSL2中继器（MAX96717加串器）---GMSL2--->J6域控（MAX96722解串器）---MIPI--->J6域控（SoC）。GMSL2中继器配置为透明传输，可以中继FSYNC信号和IIC信号（通过逻辑分析仪确认无误），但是J6域控接收图像失败，dmesg关键log如下（我想问一下这个错误是啥意思）：
