debugging. After system has booted up, it can be set

via /sys/module/acpi/parameters/debug_layer.
CONFIG_ACPI_DEBUG must be enabled for this to produce any output.
Available bits (add the numbers together) to enable debug output
for specific parts of the ACPI subsystem:

0x400 os services 0x800 acpica disassembler.
The number can be in decimal or prefixed with 0x in hex.
Warning: Many of these options can produce a lot of
output and make your system unusable. Be very careful.
