Question about my kernel


Hi everyone,

I am running FC4. uname -r gives me 2.6.11-1.1369_FC4

I am running an Athlon processor, why does yum want to give me the i686 kernel upgrade? Isn't this just for Intel processors? Is there harm in accepting this update? As of now I've bypassed it.

The "i686" labekl refers to the intel pentium-pro and it's equivalents - so it really depends on the CPU flag in the kernel. Try looking at

uname -a

Yeah, this is what I worry about:

Linux localhost.localdomain 2.6.11-1.1369_FC4 #1 Thu Jun 2 22:55:56 EDT 2005 i686 athlon i386 GNU/Linux

The machine hardware name is listed as i686. What's up with that? I never asked for an i686 upgrade. I don't know, things seem to run fine. Is there any immediate reason to upgrade my kernel?

Is it an Athlon or Athlon64? Athlon then yes, i686 is fine. The old AMD K6 was an i586 CPU that supported most i686 extensions but not all. The Athlon is i686 and Athlon64 (incl. dual-core) are amd64 or x86_64.

And also I just wonder why yum wants to give me i686 kernel upgrades to begin with.

Yes it's just an Athlon 2500+

When I upgrade my kernel, does every rpm I installed w/ yum have to be reinstalled? Is there anything that will stick around, i.e. programs that I've installed?

Nope, just upgrading the kernel won't negatively impact any other software you have installed except drivers. Now most drivers are kernel modules that will come with the new package but things like nvidia drivers, wireless drivers etc will need to be reinstalled.

Excellent. I understand that upgrading your kernel is usually for security reasons, is there any other good reason for kernel upgrade? Because I'm always up for an upgrade, but reinstalling the drivers sounds, well, not fun. Especially this usb-wireless adapter, what a mess!

Very good - you may also want to upgrade kernels to take advantage of new features or better support which may be built in. Laptop owners like to keep well uptodate for power management reasons for eg.

You'll find out in time.

YUM wants to give you kernel updates because they are there.
Personally, I disable the update notification and remove that icon from my panels.
