Compile Kernel 2.6 under Debian Sarge

Do you see any error message?

 

Hi,

yes I do.


when booting up this is written right before it stops:

Code:

mkdir: cannot create directory '/devfs/VG': Read-only file system
mount: unknown filesystem type 'devfs'
   Unable to find volume group 'VG'
unmount: /dev: not mounted
unmount: devfs: not mounted
mount: unknown filesystem type 'devfs'
JFS: nTxBlock = 8192, nTxLock = 65536
unmount: devfs: not mounted
pivot_root: No such file or directory
/sbin/init: 432: cannot open /dev/console: No such file
Kernel panic - not syncing: Attempted to kill init!

And after that it hangs, I've to reset the server.

 

I've fond this link: http://lists.debian.org/debian-amd64/2005/10/msg00848.html

 

Hi,

thanks for the reply.

I just want to say that this is the first time I've compiled a kernel.

I tried what was suggested as in: http://lists.debian.org/debian-amd64/2005/10/msg00854.html

But I get the same error message when booting up.

Edit: Im not using AMD64 version of Debian.

 

i flllow the instructions i remote recompile 2.6.14 with grsec but achine dont respond

but i can ping it.
i think 2.6 change run level to some other mode with minimal network?

your ideas?

ok
i check there is no error (on first look) system is booting corectly
i log on machnine (not remote) normaly but sshd is notstarted simple there is no services?? i try /etc/initd.d/ssh but there is no output??? just back me to prompt

 

Anything in the logs? Any errors in the output of

Code:

dmesg

?

 

i compile it again with same steps.
but i put in /etc/fstab /sys sysfs and now its working

 

I've got a problem - I'm new to debian, and did an apt-get upgrade to upgrade stuff that needed to be done.
It upgraded the kernel, and now I can't boot - I've got the same error as some others, where it wont find /dev/hda1.

This is probably going to make me sound like a real n00b, but I haven't changed the initrd from the .img-2.6.15......... to 16, because there is no img file in /boot for the new kernel.
Any advice?? Like I said, I can't boot into debia, so I'm in pretty unfamilular territory now, except for a trusty knoppix boot disk.

 

I don't see a 2.6.16 kernel in your menu.lst...
Anyway, you can create a ramdisk like this:

Code:

cd /boot/
mkinitrd -o /boot/initrd.img-2.6.8.1 2.6.8.1

(this example is for a 2.6.8.1 kernel, adjust it to your needs).

 

Can I make a RAM disk outside of being in Debian - If so, will knoppix work, and do I just use the usual bash prompt?
Also, what kernel number should I use, I'm not sure what it updated to - is there any way I can find out in system logs or something??

Thanks heaps!

 

You should make it on the system where you installed the new kernel.

Have a look at the /boot directory - you should find your new kernel there.

 

What am I looking for in the /boot directory of the drive that holds Debian (As I said, I can't boot into Debian therefor I have to mount the drive in a knoppix session to see the contents of the drive)

In the /boot directory I have:
System.map-2.6.15-1-486
vmlinuz-2.6.15-1-486
config-2.6.15-1-486
initrd.img-2.6.15-1-486
grub/

My /boot/grub/menu.lst points to the /boot/initrd..... (initrd) and /boot/vmlinux..... (kernel) files and yet still wont boot.

 

You only have a 2.6.15-1 kernel in /boot, but there's already an initrd.img for it...

 

Cannot get 2.6.8 kernel to work

I installed Debian 3.1r2 today and wanted to upgrade the kernel (2.4.27) to (2.6.8). Tried a kernel image from the Debian dist with the resulting error

Code:

pivot_root: No such file or directory
/sbin/init: 432: cannot open dev/console: No such file
Kernel panic: Attempted to kill init!

I tried following your walkthrough to compiling a kernel. I even loaded my config for 2.4.27 to start from and it comes up with same error. Some output I noticed just prior to the error looks like this:

Code:

RAMDISK: cramfs filesystem found at block 0
RAMDISK: Loading 3580 blocks [1 disk] into ram disk... done.
VFS: Mounted root (cramfs filesystem) readonly.
Freeing unused kernel memory: 204k freed
initrd-tools: 0.1.81.1
NET: Registered protocol family 1
SCSI subsystem initialized
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebux=xx
ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping probe
hdc: SONY DVD+/-RW DW-Q58A, ATAPI CD/DVD-ROM drive
Using anticipatory io scheduler
ide1 at 0x170-0x177,0x376 on irq 15

It appears like it can't find the primary hd when loading the 2.6.8 kernel, but works fine under 2.4.27.

Any ideas what I need to do differently?

 

Why don't you install Sarge with a 2.6.8 kernel right from the beginning? When you boot from the install CD, type linux26 at the boot prompt, and Debian will be installed with kernel 2.6.8.

 

Ok I tried installing with linux26 and think I've come to the real problem. During the installation I get this error:

An excerpt from the syslog (during installation) reveals this:

Any ideas why it won't seem to detect my hd properly under 2.6.8 but it works fine with 2.4.27?

 

Is it some kind of exotic hard disk?
Make sure it's connected properly.

 

No this is not 'some kind of exotic' hard disk. It is a Hitachi HTS541060G9AT00 60 GB Ultra-ATA laptop hard drive. In a Dell Inspiron 6000. Like I said before, it loads up fine using kernel 2.4.27, but I need at least 2.6.8. I read somewhere the the 2.6 kernels went to ide-core instead of the ide-mod, ide-probe-mod and all that. I see that the ide-core module loads fine but it still doesn't explain why the I/O resource for the ide0 is busy when trying to detect hardware.

I am not sure what else to try. I've tried passing boot parameters such as hd=116280/16/63 to describe the CHS of the hd.

 

There must be a bug in the 2.6.8 kernel. I downloaded and compiled the 2.8.16.11 kernel and it loaded up fine. Searching the internet I found a lot of people had the same problem with the Dell Inspiron 6000 and the 2.6.8 kernel.

 

partial compilation

hi,
Is there a way to compile just the updated files ? I know that in the vanilla kernel, doing a make compiles just the updated files and builds the kernel. However, under my sarge, doing a:

fakeroot make-kpkg --initrd --revision=custom.1.0 kernel_image

does not have the same behaviour.
