查看當前正在運行的進程發現kipmi0進程占用率達到100%
kipmi is supposed to run with low priority. When you say it consumes 70-90% 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 70%/90% 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.
解決方法：
臨時降低
echo 100 > /sys/module/ipmi_si/parameters/kipmid_max_busy_us
永久生效（系統重啟生效）：
echo "options ipmi_si kipmid_max_busy_us=100">/etc/modprobe.d/ipmi.conf
