FC6 Anaconda installs i586 kernel on i686 processor workaround

[Max Power]

I just found a post that addresses the issue with Anaconda installing the FC6 i586 kernel on systems with an i686 processor:

https://www.redhat.com/archives/fedo.../msg03725.html

Here's the text:

I did:
yumdownloader kernel-2.6.18-1.2798.fc6.i686
sudo rpm -Uvh --replacefiles --replacepkgs \
kernel-2.6.18-1.2798.fc6.i686.rpm

yumdownloader comes from the yum-utils package.

His instructions work like a charm. Many thanks to Lars for this...this problem has been driving me crazy for a couple of days!

Hi Firewing1, you can use rpm -Uvh --force kernel-2.6.18-1.2798.fc6.i686.rpm instead.
if you see man --force is short way to write --replacefiles --replacepkgs --oldpackage.

I did this and here is what I got:

[futz@xblade ~]$ sudo rpm -Uvh --force kernel-2.6.18-1.2798.fc6.i686.rpm
Preparing...                ########################################### [100%]
   1:kernel                 ########################################### [100%]
device-mapper: table ioctl failed: No such device or address
device-mapper: table ioctl failed: No such device or address
device-mapper: table ioctl failed: No such device or address
[futz@xblade ~]$

I tried changing the kernel once before, following some other forum poster's instructions and could never reboot again. On my boot attempts before reinstalling, I saw those same device-mapper errors.

The first time I tried to replace the i586 kernel with the i686, I tried using someone's suggestion of a similar command using --force kernel. I immediately got "grubby" error messages. When I tried to reboot, grub couldn't find any kernels and I had to reinstall. There appears to be some kind of difference in the commands.

I followed Lars' directions to the letter and everything went smooth.

These same directions are now listed as the workaround on Fedora Wiki under Common Issues:

Well, the replaced kernel works, but I think those errors are something to do with device-mapper not working right. This box has multiple distros on it on various hard drives/partitions. I'm unable to mount the other drives/partitions (yes I am doing it right) from Fedora. All I get is errors like this:

mount: /dev/sda2 already mounted or /media/sda2 busy

I know for sure that the device is not already mounted or busy, so now I'm unsure what to do.

I can mount them in sabayonlinux and suse.

[root@localhost ~]# rpm -Uvh --replacefiles --replacepkgs kernel-2.6.18-1.2798.fc6.i686.rpm
Preparing...                ########################################### [100%]
        package kernel-2.6.18-1.2849.fc6 (which is newer than kernel-2.6.18-1.2798.fc6) is already installed

Try also using this arg:
--oldpackage

When installing Fedora core 6 you can choose what kernel you install ,The default seems to be i586 to change this to i686 at install just use this option at CD/DVD boot

linux i686

If you have already run updates, and updated to the -.2849- i586 kernel, the above procedure (in post #1) will fail.

These altered commands below will fix the problem. Note the red characters. These are the changes that have been, and must be made.

 su -c "yum install yum-utils"

 yumdownloader kernel-2.6.18-1.2849.fc6.i686 

su -c "rpm -Uvh --replacefiles --replacepkgs kernel-2.6.18-1.2849.fc6.i686.rpm"

These changes, however, are only valid until there is another updated kernel made available.

Or just do

yumdownloader kernel.i686

which will automatically grab the latest i686 kernel... From there:

su -c "rpm -Uvh --replacefiles --replacepkgs kernel-*.i686.rpm"

Nice! I'm gonna quote you on that.

I typed in linux i686 when i went to install and I think it worked, can someone tell me the command to check in terminal to make sure it worked & im using i686? Thank you in advance.

Ok i found the command and got this:

[Captn@localhost ~]$ rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n"|grep kernel|sort
kernel-2.6.18-1.2798.fc6.i686
kernel-headers-2.6.18-1.2798.fc6.i386
[Captn@localhost ~]$

Does this look correct?

Your kernel is fine
