Kernel compiling

[kjbunete]

Well, since the Linux fourms are getting a little active now, I have a question.

I was compiling the Kernel 2.6.6 for my M10o and I got some Kernel warnings and what nots. Normally I just ignore them and go along my way. Well, I got bored and I went though and addressed each warning. So when I compiled, It ran smoother than ever. I also removed some extra modules that are not needed for my system. I compiled as so.

Make oldconfig
Make xconfig
Time Make
Time Make modules_install
Mkinitrd /boot/initrd-2.6.6.img 2.6.6

Then I copied the the bzimage to vmlinuz-2.6.6 & System.map to System.map-2.6.6 & .config to config-2.6.6

Then I booted, then I got some PCI controller error. That was easy to fix, I changed the option of "MMconfig" to "Any" and I no longer get that error. Now I get a Kernel Panic And these are my last three lines of the screen

Resume Machine VFS: Cannot open root device "306" or unknown-block(3,6)
Please Append a correct "Root=" boot option
Kernel Panic: VFS: Unable to mount FS on unknown-block(3,6)

If someone could tell me what modules I need to select, and I know that you can not tell me the exact name of the modules. And I do not what you to. I just want to know if I have to add modules to my filesystems, ATA,IDE..., ect. Also, I have completly disabled the MTD's for my computer. I have spent some time looking at my existing Kernel (this is 2.6.6 as well, I just wanted to "slim" my kernel for perfomace reasons, and I was bored) and my Memory set up and I saw that it was not using any of these. Could it be that I did this that I'm getting my VFS error? Because I remember that I saw something about Vurtial File Systms and I look at that I think it means VFS.

oh boy I fell as I rambled, Does anyone know what I'm talking about?

It might be a stupid solution/mistake, but if you're one of the sillyheads that use lilo, did you run lilo after the copying?

And are you **sure** your lilo.conf or menu.1st is correct? No capitals where there should not be capitals?



Well, I'm off to bed, or gonna config some splashimages now, so I'll just have a closer look at your post tomorrow.

LOL,


Don't worry about it, I figured it out. I got a little to click happy and I completly disabled all PCI IDE controllers. As soon as I reinstalled those modules, recompiled and then ran what I needed. I was good! It started loading Mandrake 10! Now I just need the Interactive setup to pasue for a while so I can read what is passing and what is failing. So I can fix those issues, because I can't start X or KDE with this kernel. As soon as I get all of these situated to the point that it is just right for my system, I'm making a copy of my .config on to a floppy disk!

Thanks a lot though Trillian!


P.S. Yes I'm using Lilo! (Only because I have not told it to go to grub yet! )

Just a general tip:

After a kernel upgrade a lilo -v -v is a good thing to test before rebooting

That will test lilo to make sure your config is correct. The results should be similar to this:

[root@yoursystem root]# lilo -v -v

Way the go!
Why won't X work?

PS
go for grub, it owns :o

[kjbunete]

I do not know why, so I just recompiled it again using the same configuration and it works like a charm. What I think is during my first compile, the power saged to the point that the computer almost shut down, but then it came back in full. I do belive that it was the problem. Also, just for you Trillian. I took the time and I changed Lilo to grub! Boy did I miss it!

Thank you trillian for your suggestions!

Ha, neat!
