control method, with respect to putting devices into
low power states, to be enforced (the ACPI 2.0 ordering
of _PTS is used by default).
- s4_nonvs prevents the kernel from saving/restoring the
- ACPI NVS memory during hibernation.
+ nonvs prevents the kernel from saving/restoring the
+ ACPI NVS memory during suspend/hibernation and resume.
sci_force_enable causes the kernel to set SCI_EN directly
on resume from S1/S3 (which is against the ACPI spec,
but some broken systems don't work without it).
controller
i8042.nopnp [HW] Don't use ACPIPnP / PnPBIOS to discover KBD/AUX
controllers
+ i8042.notimeout [HW] Ignore timeout condition signalled by conroller
i8042.panicblink=
[HW] Frequency with which keyboard LEDs should blink

If there are multiple matching configurations changing
the same attribute, the last one is used.
- lmb=debug [KNL] Enable lmb debug messages.
