After some grepping I realized these are Debug messages from DSDT , however my kernel does not have ACPI_DEBUG enabled. I found out the module triggering this, on this Laptop is ideapad_laptop , but looking at the code I cannot see what would causes that. Also on the same Laptop with any 5.0.X kernels I cannot see these. ~$ grep -i ACPI_DEBUG /boot/config-5.1-fw1 # CONFIG_ACPI_DEBUGGER is not set # CONFIG_ACPI_DEBUG is not set # CONFIG_THINKPAD_ACPI_DEBUGFACILITIES is not set # CONFIG_THINKPAD_ACPI_DEBUG is not set .. dmesg .. ...
