DIsable kernel's irq balance feature

muczyjoe · 2008-10-20 20:08:01

$ zcat /proc/config.gz | grep IRQBALANCE
CONFIG_IRQBALANCE=y

Default Arch kernel has (from 2.6.27?) irq balance enabled, which is bad, as powertop says. Please disable it!

It's probably enabled for a reason. If it gives you trouble, you can always disable it from within your boot loader's configuration .

I've searched for it, but couldn't find it.
How can I disable it on kernel command line?

Add 'noirqbalance' (w/o the quotes) to your kernel cmd-line.

I think, that worked. Thanks!

A bug has been filed for this -> http://bugs.archlinux.org/task/11791
Maybe powertop was right...

I added noirqbalance to kernel boot parameter in menu.lst but powertop always suggests to disable it.

This is my menu.lst entry:
