Adding module-parameters in Grub

Hi Community,

Im using the following line in /etc/modprobe.conf to make my thinkpad stop whining:

options processor max_cstate=2

now i want to add this directly to the grub kernel line in menu.lst, i tried

kernel /vmlinuz26 root=/dev/sda5 ro processor max_cstate=2

and

kernel /vmlinuz26 root=/dev/sda5 ro processor.max_cstate=2

but both has no effect.

Any ideas?
regards,
Fabian

modprobe.conf is the right place for it, because processor is compiled as a module. You would only use grub's kernel line if it was built in to the kernel.

So there is no way to get this working throw grub (beside building a custom kernel)?

Correct. There is also no need to do it with grub.

There is. In a noisy area i dont need the options, but in a quiet one i do. I want to decide on bootup if i use the kernel with or with out the paramters.

Re: Adding module-parameters in Grub

Then you probably want to build two initrd's and make an extra entry in grubs menu.lst.
