Is that the content of /proc/cmdline, or your perusal of some latter portion your Grub menu file? If the former, why are you using it???
Felix, it is in fact the contents of the /boot/grub.d/grub.cfg. to give you
what you requested, rather than asking why you requested it:
more /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.8.9-5-desktop root=UUID=a3b45d4e-a3dc-4e0f-9b24-2d0d4f65c221 noapic nolapic apm=off noresume edd=off powersaved=off nohz=off hires=off processor.max_cstate=1 nomodeset resume=/dev/disk/by-id/ata-ST9320421ASG_5TJ0Q4HY-part2 splash=silent quiet showopts [snip]
Hmm, when I compare that to my /proc/cmdline, the short answer would be to remove the following options:
noapic nolapic apm=off noresume edd=off nohz=off hires=off processor.max_cstate=1 nomodeset
Now, if you are unsure wether or not you NEED one of these options, start the remove action with:
edd=off (Monitor modi detection stuff, uncritical on most systems)
hires=off (hires timer, uncritical on most systems)
noapic, nolapic (every modern (past 2003/2004) needs apic to controll interrupt handling, no apic = nosmp)
apm=off (system power management, only need for shitty BIOS)
nohz=off (AFAIK Intel speedstep / AMD Cool'n'Quiet need that removed)
nohz is for enable/disable dynamic timer ticks. It helps with power savings, but has little to do with Intel SpeedStep / AMD Cool'n'Quiet, other than allowing the CPU to go truly idle by the system not triggering timer interrupts CONFIG_HZ times a second when it's unnecessary.
