D1s使用rndis的网口传输SFTP文件，会死机

Maihuanyi LV 5

通过RNDIS虚拟网口登录ssh，ssh的操作都是正常的，但使用sftp传输文件时会死机
死机后的log如下：

root@TinaLinux:/# random: sshd: uninitialized urandom read (32 bytes read)
random: sshd: uninitialized urandom read (32 bytes read)
random: sftp-server: uninitialized urandom read (32 bytes read)
random: sshd: uninitialized urandom read (32 bytes read)

有人遇到这样的问题吗，或者有什么解决的思路分享一下。

WhycanService LV 8

看着是random的问题，urandom没有初始化

Maihuanyi LV 5

@whycanservice 等random初始化成功再连接sftp，传送文件还是会死机。

WhycanService LV 8

@maihuanyi

dmesg -n 7 配置高loglevel查看报错函数点

目前看到是 mm/slub.c 出问题，但是没有具体函数参考

Maihuanyi LV 5

@whycanservice 打开了也看不到那个函数报错

Eason LV 3

你好，请问解决了吗

epoko LV 2

遇到了同样的问题，使用rndis向开发板传输大文件时就会报错，反向传输则没问题，详细日志如下
