      我用的是RM500U-CN的 现在CM5有集成5G模组卖的吗?
      我用USB3.0接的模组 编译了内核 可以用 但是这个内核如果接USB无线网卡 内核就会崩溃
      内核是按照5G模组的文档来改的

        这个要看具体的log信息,是驱动有冲突还是什么问题,你可以使用PCIE的网卡暂时规避这种问题,CM5的机器可以支持多种型号的PCIE+USB网卡。
        这个模组目前是针对CM5的笔记本设计的,CM5-EVB暂时用不了。

          这个就是当时的log
          这一块内核崩了 系统还可以正常运行
          用的是CM5支持的无线网卡

            这个是RTL的驱动注册有问题,你可以加LOG信息在rtk的驱动里边跟踪一下,定位到具体哪里报异常。然后再想办法解决。
