Two Kernels a problem?


I upgraded my kernel in Fedora Core 2 and now I have a ton of errors when I boot. When I boot into the old kernel the errors don't appear! Is it okay to leave the new kernel on the system and just not use it, but rather use the old one insetead?

Sure, it's a just a file (group of files if you use modules).


Cheers,

Yep, you can have multiple kernels. Only the one you boot gets used.

Whenever you install or compile a new kernel you should always leave the old kernel in case the new one doesn't work, as in your case...

Get yourself the latest for kernel.org and see if you can compile a working one maybe...

Short answer: yes. (But make sure you have /usr/include/linux pointing to the right kernel version if you're going to compile programs).

The errors you are getting are probably related to module dependencies not being set up properly; you may be able to fix them using
Code:
depmod version
where version is the kernel version string for the kernel that is “broken”.

This type of problem can also be caused by having an out of date binutils package (see /usr/src/linux/Documentation/Changes).

Thanks

Thanks - great stuff. What an incredible community. The Linux community and the Mac community are both SUCH a pleasure.

Hey, Microsoft's CFO is coming to our business school to give a speech and the school paper is trying to arrange for me to interview him and write an article. I'll take (G Rated) votes on what to ask him!

jeopardyracing -- Congrats on solving the problem and thanks for posting back with the positive feedback. Additionally, if this interview looks like it might happen, I would urge you to check out the new LQ News forum I'm pretty sure that this kind of interview would be perfect for that forum, and you might consider contacting jeremy if it looks likely.

In any event congrats on solving the problem. -- J.W.

I'll do that - the editor of the paper is trying to get the time scheduled with the guy - what I can do is post the article to the forum once I have written it. The CFO is here to recruit MBAs so I gotta be a little fluffy and not be too tough, but you bet your life Linux will be part of the conversation.

Excellent -- IMO I'd say a few Linux questions certainly would be reasonable, ie, "What kind of stragetic challenges does Linux / Open Source pose to Microsoft's future in your view, and how does the company plan to address those challenges?", etc. I'd be particularly interested in an answer to that kind of question from the perspective of the overseas market -- I thought this article was an incredibly interesting discussion of Microsoft's pricing structure in terms of the cost of XP relative to the per capita income in various countries.

Anyhow, as I said if the interview looks like it will happen I would really, really encourage you to contact jeremy -- J.W.

Interesting reading indeed :)

I still wonder how people calculate a lower TCO for
windows than Linux machines. Basically it's all based
on the fact that they assume everyone already HAS
several MCSE/MCP working for them while they'd
need to get an RHCE or LSI cert if they moved. :)
Not really a valid approach as far as I'm concerned.


Cheers,
Tink

Overseas

That's kind of what I was thinking about - focusing my Linux questions on the temporing effect they have on overseas growth. Looking at the software picture and Asia, it almost feels like the auto industry looking at Japan in the 60s and 70s.
