veket22-启动时urandom随机数资源不足的问题

宵夜鸟

var/log里面提示每次启动都会报错，内容如下
Apr 13 07:09:09 veket user.notice kernel: [   11.056069] random: alsactl: uninitialized urandom read (4 bytes read)

隔一会儿才会提示
Apr 13 07:09:14 veket user.notice kernel: [   21.810806] random: crng init done
Apr 13 07:09:14 veket user.notice kernel: [   21.810809] random: 25 urandom warning(s) missed due to ratelimiting
网上说是启动时随机数资源池不够，提供了几个方法都没有效果（比如装haveged或是在etc/sysctl.conf里面加语句等等），有没有大佬知道这个该怎么解决呢？现在我判断声音系统启动不正常大概率就是这个原因。

还有一种我看不懂的处理办法，说是给内核打后面这个链接里的patch。https://lkml.org/lkml/2018/7/17/1279
然而新手看过以后表示：“给内核打patch”是一种什么操作？完全不知道如何实践……

这个要重新编译才行呢，要几个小时的
