Compile Kernel 2.6 under Debian Sarge

[falko]

Do you see any error message?

Hi,

yes I do.


when booting up this is written right before it stops:

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.../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.../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

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.
Here's a copy of my menu.lst

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:

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!
