xilinx AXI-DMA/AXI-VDMA核导致内核启动报rcu: INFO: rcu_sched detected stalls on CPUs/tasks:

Question

目的：应用官方提供的dma-proxy.c 测试AXI-DMA在loop下的数据收发。
问题：参照xilinx官方提供的文档https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1027702787/Linux+DMA+From+User+Space+2.0%EF%BC%8C%E6%90%AD%E5%BB%BABlock Design，添加相应的设备树节点，用petalinux构建工程，工程构建过程中未报错，内核版本未5.4.0，但是将生成的启动文件及内核镜像放入SD卡中启动的时候（板卡ZCU104）内核无法启动，提示：

Block Design、设备树、内核配置、问题截图详见附件，请问帮忙看看什么原因吗，谢谢。

在system-user.dtsi文件中添加设备树：
/ {
dma_proxy {
compatible ="xlnx,dma_proxy";
dmas = <&axi_dma_0 0 &axi_dma_0 1>;
dma-names = "dma_proxy_tx", "dma_proxy_rx";
dma-coherent;
} ;
};
