will kernel upgrade from 2.4.2 to 2.4.20 impact other software like gnome, dameons,..


I am rather new to linux. I have RH7.1(2.4.2 kernel) and I want to upgrade the kernel to 2.4.20, which I downloaded from kernel.org. I have two questions.

1. If I upgrade the kernel to 2.4.20 and implement it successfully, will it affect other surrounding pgms and software like gnome, kde, various daemons, and others. If it does, how do I find out what and how to upgrade the impacted pgms & software?

2. I am not still clear the differences between the distirbution such as RedHat and Susie, and etc.. if they all share the same source kernel and have Gnome, and Kde and other similar programs. Maybe this is too basic and stupid questions.

Thank you very much.

Well, you can try it out. I doubt it would make things not work though, as long as you have things setup the same way, more importantly, have the necessary things enabled. But yeah, you can try it out, just make a seperate entry in your bootloader, don't overwrite your existing kernel, and then if it doesn't work out well, you can always boot back into your current, working, existing kernel and tweak things around some more until it does work.

Cool

MasterC, thank you for the reply.

BTW, you have a very good "Getting Started...". I printed out to review and learn some more.

I will save the old kernel and try out the new one.

RedHat8.0 probably not = RedHat7.1 + upgraded kernel to 2.4.20(if 8.0 has 2.4.20, maybe 2.4.18).

RedHat8.0 has, I think, has more than 3 CD-rom, so I think other auxiliary softwares have newer versions and interact better between them.

Could someone please point the website, if there is any such website, that shows some technical difference between distributions, not just feels and looks?

Thank you.

I still don't think you'd have a problem, as long as all you wanted to do was update the kernel. Software will have different releases, but it's still a 2.4.x kernel series, so you should be fine.

Cool

be interesting to see what happens during such a large kernel jump.

Only think you should need to worry about are modules not in the kernel, such as nvidia drivers or for me my webcam. These may need to be recompiled after changing kernel version.

Thank you MasterC. The web page is an excellent chart showing the major software versions in each distrib.

Thank you acid2000 for the comment.

I will try to upgrade the kernel to 2.4.20 this week, and I will post any questions or the result.

Thank you very much.

I ,for now, successfuly upgraded the kernel from 2.4.2 to 2.4.20 without encountering any problems in compiling the kernel and booting to the new kernel. It may be too early to tell.

However, the ACPI to power off by itself on shutdown is not quite working yet. It worked only one time, the first time I used the new 2.4.20 kernel, but after that it is not working with hwsleep-0178 error. One of the reason that I upgraded to new kernel is to use the ACPI to power off linux by itself.

I use lilo and I used the new map that came with the 2.4.20. Still, I do not know the function of the map. When I booted using 2.4.2 kernel with 2.4.20 map, it still boots ok. Do I have to use the different map for the different kernel? Could some expert answer this question?

Thank you very much.

Sweet! Now just gotta work out the kinks, get the ACPI working consistently, and figure out your Map question. Here's my theories:

ACPI: Got really no clue. However, did you build it into the kernel, or module it? Maybe it's not calling all the modules needed if that is case? Also, check /var/log/messages to see if it spit out anything about the "error".

Map: I personally keep the old System.map file and the new one. And I symlink whichever one for the kernel I consistently boot. I don't think it's a huge deal for your old kernel unless you are compiling against it? There is a thread on this somewhere on the board where Trickykid pointed us towards a site that explains the mystery behind the System.map file. I think you may be able to find it in the Slackware forum.



Cool

MasterC. thank you very much for the prompt reply.

I compiled the ACPI into the kernel 2.4.20, not as a module. I will look at the /var/log/messages to see if I can figure out.

As you suggested, I will search this site for more info on the System.map.

Thank you very much again.

You're welcome If you aren't sure what it to look for in /var/log/messages, go ahead and either email it to me and I'll host it for you, or host it up somewhere and post a link to it (It's way to long usually to post the entire message right here directly), I'll be happy to look through it and see if I can find the error, and I'm sure others will as well

Cool

Here the link to the thread about the System.map file (one of them at least).

Kernel images and System.map Thread

I'm not sure if this is the one MasterC was referring to, but it explained some things for me.

Thank you Dark_Helmet for the help.

I went to the web site and printed out for digesting.

THank you again.

Thank you for your generous help.
I sent you my /var/log/messages thru e-mail after many attempts to attach the file or copy and paste, for your review.

As I mentioned, the ACPI power off does not fail all the time. So far about 3 times the power down from the new linux kernel 2.4.20 succeeded and I do not know what make it work correctly.

As I also pointed out, the /var/log/messages also contains boot messages from the old previous kernel 2.4.2.

I looked at the message, but since I am a novice, I do not seem to able to find out anything from the message. I do not have my own web home page like you, yet. I connect to internet using 56K modem.

Thank you very much again.

It appears that the file still didn't get attached, not sure why. Anyway, go ahead and try emailing it to me at: masterc@masterc.no-ip.org You can either attach the file /var/log/messages or you can paste the entire thing in, either way is fine with me (but if possible I'd prefer the simple attachment of the file rather than a pasted message).

If that still fails, I'll be happy to setup a temp ftp user for you so you can upload it to me via ftp. That way it will be as easy as drag n drop browser window to window.

In the meantime, see if it works only at specific times (or doesn't work only at specific times) meaning, whether you are in X or not, if you are root or not, and things of that nature.

Cool
