详细叙述

x86架构
最新源代码编译后CPU load高

Mem: 314532K used, 1597772K free, 33540K shrd, 1816K buff, 125520K cached
CPU:   1% usr   5% sys   0% nic  92% idle   0% io   0% irq   0% sirq
Load average: 0.68 0.58 0.60 2/183 7905
  PID  PPID USER     STAT   VSZ %VSZ %CPU COMMAND
29553     2 root     RW       0   0%   5% [kworker/2:2+eve]
26019     1 root     S    1292m  69%   2% /tmp/etc/passwall2/bin/xray run -c /tmp/etc/passwall2/acl/default/global.jso
32381  5248 root     R     1156   0%   0% top

这个5%的system就是 kworker进程， 也不知道内核在忙啥

详细日志

我抓了个快照

echo l > /proc/sysrq-trigger

结果如下：（几次都得到这样的）, CPU-2也不知道在干啥
