Kernel Panic...I did something wrong, but I do not know what

debian111 — Mon, 06 Feb 2006 02:40:06 GMT

I compiled kernel 2.6.15 last weekend and some problems occurred during my work
Distribution is Debian Sarge

in /lib modules is as follows

tdebian:/lib/modules/2.6.15-new# ls -l
total 992
lrwxrwxrwx 1 root root 36 2006-02-05 09:52 build -> /usr/local/src/kernel/linux-2.6.15.1

lrwxrwxrwx 1 root root 36 2006-02-05 09:52 source -> /usr/local/src/kernel/linux-2.6.15.1

when I start new kernel chosing it in grub, after 5 sec I got output like bellow

modprobe: FATAL: Could not load /lib/modules/2.6.16-new/modules/dep
No such file or directory
umount: defs: not mounted

.....I cannot understand what I did wrong

If somebody know what I did wrong acording to my outputs above, please write it down, I would pritiete that.

Thank you

Shalom,

You may have done nothing wrong.

This panic may be caused by hardware support not being in the new kernel. If you need to put that support in, you need to see that the drivers installed in the old kernel are installe din the new ones.

debian111 — Mon, 06 Feb 2006 05:09:42 GMT

???
but my new kernel does not work, and I wish I can make it work because it is very important for me it works.
I mada my own .config file and I included all neccessary modules ( or not ?) and i am wondering what is problem.

Thank you for help

You are trying to install kernel 2.6.15 but got output "modprobe: FATAL: Could not load /lib/modules/2.6.16-new/modules/dep".
How is this possible? What does "2.6.16" mean?

I propose to recompile kernel according to Debian instructions:
http://www.debian.org/releases/stable/i386/ch08s05.html.en

Sergejs

debian111 — Mon, 06 Feb 2006 05:51:38 GMT

2.6.16 is just mistyping....there shoul be 2.6.15....it is set correct in /grub/menu.lst

here it is just mistyping...

Thank you

You may try starting with a working kernel configuration, for example, do could do make oldconfig, and then, add or remove the kernel modules. Better yet if you have the .config file of your working kernel, use that as baseline.

Sergejs Svitnevs — Mon, 06 Feb 2006 06:32:09 GMT

But what about "modules/dep"?
Is it also a TYPE error and we should read "modules.dep"?

Re: Kernel Panic...I did something wrong, but I do not know what

debian111 — Mon, 06 Feb 2006 07:11:57 GMT

I know what you suggest me, but look at error I got, it is confusing, I think.

I tried to use old kernel configuration as my starting position, and I did not get a correct output.
Kernel says that it cannot find file
/lib/modules/2.6.15---kernel version/modules.dep but file modules.dep is there as you can see.

Anyway thank you for your suggestions and help,

regards

debian111 — Mon, 06 Feb 2006 07:16:04 GMT

modules.dep.....
Was not able to copy/paste error I got....

modules/dep should be modules.dep...sorry people I am very tired, this problems about kernel, some other problems exshausted me.

Thank you

Sometimes, when I recompile the kernel, I have problems with LABEL= in grub.conf. Try changing the root device in grub.conf to the specific device, if it's using labels.

I haven't rebuilt my kernel for awhile, but my thoughts on are:

The key might lie with the line "umount: devfs: not mounted" (I've added the v which seemed to be missing) Your devfs does not appear to be mounting. I'm guessing devfs is your problem as the FATAL came from modprobe and /dev/console could not be found.

Cheers

Stuart Browne — Tue, 07 Feb 2006 14:57:19 GMT

Related tot hat last post, are you sure you included the filesystem componants in the kernel?

Did you build it modular, if so did you re-build the initrd with the filesystem modules in it?

Re: Kernel Panic...I did something wrong, but I do not know what

debian111 — Wed, 08 Feb 2006 06:53:42 GMT

I have no so much experinece, could you plese be more precise, I mean can you explain it in more details, I read many HOWTOs and I got the output I posted before , so now I am in stuck, I tried the same process last night and I got the same output
when I enter in shell

dpkg -l|grep udev, I got that I am using some 0.5? I do not exacly which version, but I read somewhere that I must install udev 0.72 or later for kernel 2.6.12 or later compilation.

Shoul I install udev before kernel compiation or after kernel compilation?

Anyway I pritiete very much your help, and thank you for that.

2.6 deprecated DEVFS. Make sure you have
the appropriate stuff in /dev and remove
devfs from the boot functionality.

Replacement devfs funtionality is in udev.

Re: Kernel Panic...I did something wrong, but I do not know what

genti_1 — Wed, 29 Mar 2006 00:34:45 GMT

I have the same problem. I uninstalled devfs and installed udev.
kernel 2.6.15.1 boots fine but the 2.6.16.1 doesn't. Probably because it is custom build.

does the drive address change from 2.6.15 to 2.6.16? mine right now is /dev/sda but i have also some usb card adapter that takes 4 devs (sdb-sde) and whenever I ugrade a kernel or do something to the boot it replaces the sda with sde.

genti_1 — Wed, 29 Mar 2006 00:58:42 GMT

I think i narrowed down to initrd. I used the old initrd from the previous kernel to see what happened and from there it says that /sda was not found but i can get to a prompt.

to make a initrd i used
# minitrd -o /boot/initrd.img-2.6.16-amd64-k8

any thoughts?
