Thanks for your workaround and explanation! However in my case, I found that unmask ACPI interrupt immediately after boot will bring the CPU throttle issue back. I've fixed it by adding a 1 minute sleep: ``` [Service] Type=oneshot Restart=on-failure ExecStartPre=/bin/sleep 60 ExecStart=/bin/bash -c "echo 'unmask' > /sys/firmware/acpi/interrupts/gpe6E" ``` -- You may reply to this email to add a comment.
