If your machine hits crazy load and your processor is: Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz
Check with top what’s wrong. In my case I had load 44 without any special reason (non production server). The problem was: acpi_pad.
Kernel: ~3.10 but google say it’s also on higher Linux Kernels (4.x)
Dirty and nasty – “rmmod acpi_pad” and blacklisting the module with ” echo “blacklist acpi_pad” >> /etc/modprobe.d/blacklist-acpi_pad.conf ”
A nicer and suggested solution that I have to check: updating the bios of the server machine.
Oh, the issue is not brand-related. Some people have it on Supermicro boards, Dell boards. I’ve had it on a Lenovo server.
