What does the nohz=off command do?

I'm trying to install Ubuntu on my laptop, but it freezes at the loading screen, and I've been told this command helps it not to freeze, and it really does, but I'd like to know what it does.

Anyone?

Seriously it seems like such an easy question...

it disables dynamic ticks in the kernel.

Thanks, but ummm.... I'm not much of a Linux expert, could you tell me what that means?

It's basically a way to keep your system a little cooler and use a little bit less energy while running. For desktop users, it currently looks like there will be little need to have it on, but for servers, it might be worth it in the long run.

Nice, thanks a lot!

Nice, thanks a lot!

you need to check your system monitor though, some processors get stuck at a 100% with that setting.
