For broken nForce2 BIOS resulting in XT-PIC timer.
acpi_sleep= [HW,ACPI] Sleep options
- Format: { s3_bios, s3_mode, s3_beep, s4_nohwsig,
+ Format: { s3_bios, s3_mode, s3_beep, s3_leds, s4_nohwsig,
old_ordering, nonvs, sci_force_enable }
See Documentation/power/video.txt for information on
s3_bios and s3_mode.
s3_beep is for debugging; it makes the PC's speaker beep
as soon as the kernel's real-mode entry point is called.
+ s3_leds is for debugging; it flashes the keyboard LEDs
+ 3 times as soon as the kernel's real-mode entry point is
+ called.
s4_nohwsig prevents ACPI hardware signature from being
used during resume from hibernation.
old_ordering causes the ACPI 1.0 ordering of the _PTS
CPU-intensive style benchmark, and it can vary highly in
a microbenchmark depending on workload and compiler.
- 1: only for 32-bit processes
- 2: only for 64-bit processes
+ 32: only for 32-bit processes
+ 64: only for 64-bit processes
on: enable for both 32- and 64-bit processes
off: disable for both 32- and 64-bit processes

+ cpufreq_driver= [X86] Allow only the named cpu frequency scaling driver
+ to register. Example: cpufreq_driver=powernow-k8
+ Format: { none | STRING }
+
cpuidle.off=1 [CPU_IDLE]
disable the cpuidle sub-system
The filter can be disabled or changed to another
driver later using sysfs.
+ drm_kms_helper.edid_firmware=[<connector>:]<file>
+ Broken monitors, graphic adapters and KVMs may
+ send no or incorrect EDID data sets. This parameter
+ allows to specify an EDID data set in the
+ /lib/firmware directory that is used instead.
+ Generic built-in EDID data sets are used, if one of
+ edid/1024x768.bin, edid/1280x1024.bin,
+ edid/1680x1050.bin, or edid/1920x1080.bin is given
+ and no file with the same name exists. Details and
+ instructions how to build your own EDID data are
+ available in Documentation/EDID/HOWTO.txt. An EDID
+ data set will only be used for a particular connector,
+ if its name and a colon are prepended to the EDID
+ name.
