求工程师解决一下挂载nfs,电脑上网会卡死问题
本人在使用rk3399,用的是官方给的ubuntu16.04系统，单用是好的。因为是用于办公，所以进行了集群搭建，服务器是pc版ubuntu16.04系统，用的是nis集群服务，是用nfs将服务器home分区挂到了rk3399的系统上，集群搭建成功，开始上网的时候，浏览器在打开三个网页左右就卡死了，一开始还可以进入字符页面，过一两分钟整个开发板就死机掉了。以前在用rk3288的时候ubuntu14.04也会卡死，但后来将ubuntu14server的boot分区进行替换后，解决了这个问题，但是rk3399的却不行。3288的boot分区可以进行分解但3399的却不行，官方能不能测试一下帮忙解决一下这个问题，同时能不能提供一些解压引导和内核分区的工具。服务器采用pc版ubuntu14.04,ubuntu16.04以及centos6.9等都试过了，集群可以搭建成功，但是浏览器会出现卡机问题，应该是与nfs功能有关，远程挂载home目录后，上网或者往里面拷东西都会出现死机情况，nfs不是linux最正常的功能吗？更何况板子存储不大一般都会用到nfs的，求解决 要描述一下流程，操作细节，提供log，不然别人没法帮你分析。
三个网页就卡死，是浏览文件吗？还是正常上网？ {:4_90:}固件是1130，一边用浏览器播放 nfs 4K 视频，一边 看 youku ，一边往 板子拷贝视频，没卡死 luvings 发表于 2018-2-7 16:15

我用的也是1130，但我是挂载的服务器home目录，用Nis帐号登陆的 leung先森 发表于 2018-2-7 16:07

大概8点23分开始卡，然后 日志里面没有卡这段时间的东西，不足道为什么，从27分开始重启 这是Log截图图片
有线网络试试 luvings 发表于 2018-3-16 11:35
有线网络试试
用的就是有线网 dts 配置有问题，VDD_LOG电压偏小，造成网络工作不正常。需要重新编译dts。具体见我的帖子。
