Changing a parameter in Kernel Config and applying

Hi,

due to https://bbs.archlinux.org/viewtopic.php?id=168801 issue, I wanted to follow the fix explained here : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=665493

and actually on Arch Linux :

]# zcat /proc/config.gz | grep CONFIG_HOTPLUG_PCI_ACPI
CONFIG_HOTPLUG_PCI_ACPI=y
CONFIG_HOTPLUG_PCI_ACPI_IBM=m

So basically I want to set CONFIG_HOTPLUG_PCI_ACPI to m and apply the configuration.

What's a safe way to do that?
thanks.

Edit: You should always have a liveCD / liveUSB on hand, just in case.

Re: Changing a parameter in Kernel Config and applying

Thanks Karol ,

while I'm going through the recompilation process , is there any chance to choose the version with ABSROOT in order to skip also the broadcom bug? https://bbs.archlinux.org/viewtopic.php?id=168177

And I was interested if *before* going through the hole thing I can somehow make use of :
ls /usr/src/linux-3.0.93-1-lts/
Documentation  Kconfig    Makefile  Module.symvers  arch    block  crypto  drivers    fs  include  init  kernel  lib    mm  net  samples  scripts  security  sound  usr  virt

If I can generate the images and choose to boot from either kernel when logging in.
Big Thanks.

You can preserve the existing kernel and switch while booting.
Use the traditional method : https://wiki.archlinux.org/index.php/Ke … raditional

Retain the old kernel until you are sure the new one is fine.
