我在用着:
- 操作系统:Ubuntu 18.04.3 LTS x86_64
- 内核:4.15.0-72-generic
机器启动完成后,运行时我在内核日志中遇到以下错误dmesg
:
[ 0.000000] random: get_random_bytes called from start_kernel+0x99/0x4fdwith crng_init=0

我已经安装haveged
并rng-tools
运行:
sudo apt-get install haveged
sudo apt-get install rng-tools
尝试解决这个问题,但没有帮助。
这些错误每半小时左右重复一次。
我发现这个linux 系统,但我不明白需要做什么。
我是否应该担心这些错误?
有谁知道如何消除这些错误吗?
