Kipmi0 占用CPU 100%

查看当前正在运行的进程发现kipmi0进程占用率达到100%

kipmi is supposed to run with low priority. When you say it consumes -% of the CPUs, is that constant (does it still consume the processor when they are other tasks in the process queue that should have a larger slice of the CPU time) or the %/% comes when the machine is idle?
A second issue to investigate is whether you have pending controller issues (alarms of varying nature that are not resolved) and/or older versions of controller firmware.

解决方法：

临时降低

echo 100 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us

永久生效（系统重启生效）：

echo "options ipmi_si kipmid_max_busy_us=100">/etc/modprobe.d/ipmi.conf
