October 29, 20232 yr Author From Intel Doc "Intel® Omni-Path Performance Tuning" --quote-- Avoid acpi_pad Consuming CPU Resources acpi_pad is a module ACPI Processor Aggregator Driver. It is supposed to handle high core count processor power management. Unfortunately, the driver can cause a system to run acpi_pad and consume 100% of each core. A simple workaround is to blacklist acpi_pad by adding the following line to /etc/modprobe.d/blacklist.conf: blacklist acpi_pad This will keep the acpi_pad driver from loading at boot time. If you need to remove acpi_pad without a reboot you can use: modprobe –r acpi_pad This removes the driver. However, note that the driver will restart upon a reboot. --end quote-- modprobe –r acpi_pad worked. modprobe acpi_pad if you want to reload it. IMHO, this is an old Linux bug. CPU E2697v2 @Squid
