acpi.debug_level= [HW,ACPI]
Format: <int>
Each bit of the <int> indicates an ACPI debug level,
1: enable, 0: disable. It is useful for boot time
debugging. After system has booted up, it can be set
via /sys/module/acpi/parameters/debug_level.
CONFIG_ACPI_DEBUG must be enabled for this to produce any output.
Available bits (add the numbers together) to enable different
debug output levels of the ACPI subsystem:
0x01 error 0x02 warn 0x04 init 0x08 debug object
0x10 info 0x20 init names 0x40 parse 0x80 load
0x100 dispatch 0x200 execute 0x400 names 0x800 operation region
0x1000 bfield 0x2000 tables 0x4000 values 0x8000 objects
0x10000 resources 0x20000 user requests 0x40000 package.
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.
