A bit more elucidation on acpi-user-options, please
acpi-user-options
Below is a handy dandy listing for a common question. What
"acpi-user-options" should I use when I ran into ACPI (Advanced
Configuration and Power Management) problems?
From the user input "acpi-user-options," it gets converted into a
kernel variable acpi_user_options. See acpica_process_user_options().
The options are defined at acpica.h
#define ACPI_OUSER_DFLT
0x0000
#define
ACPI_OUSER_ON
0x0001
#define
ACPI_OUSER_OFF
0x0002
#define ACPI_OUSER_MADT
0x0004
#define ACPI_OUSER_LEGACY 0x0008
Here are the meanings for each.
0x0 = Switches system into ACPI mode and uses ACPI tables for IRQ
routing (default)
0x1 = Forces use of ACPI interpreter even if system BIOS is too old or
blacklisted
0x2 = Disables use of ACPI interpreter
0x4 = Uses ACPI tables only at the PSM module to enumerate CPUs (no IRQ
routing)
0x8 = Leaved the system in “legacy” mode, identical to default
acpi_intp behavior
In general, you start with acpi-user-options=0x8
