 Posted: Mon Aug 27, 2007 12:54 am Post subject: wrong kernel is loading |
 |
|
I am seeing some strange behavior.
It seems that my system is coming up under the wrong kernel and I can not figure out why.
Here is what I did:
Get rid of all old sources
| Code: | | # emerge -C gentoo-sources |
get the latest version
| Code: | | # emerge gentoo-sources |
verify that I have only the right src I want
| Code: | # ls -al /usr/src
drwxr-xr-x 20 root root 4096 Aug 28 00:18 linux-2.6.22-gentoo-r5
lrwxrwxrwx 1 root root 32 Aug 27 23:19 linux -> /usr/src/linux-2.6.22-gentoo-r5/
|
configure the kernel
| Code: | # cd /usr/src/linux
# make menuconfig
|
make the kernel
| Code: | # make clean && make && make modules_install
# mount /boot && make install
# make modules_install
|
verify that the /boot looks right, and the boot image is pointing to the new kernel
| Code: | # ls -al /boot
total 13399
drwxr-xr-x 5 root root 1024 Aug 28 00:17 .
drwxr-xr-x 21 root root 4096 Jul 11 05:28 ..

-rw-r--r-- 1 root root 2366960 Aug 28 00:17 vmlinuz-2.6.22-gentoo-r5
|
update grub to point to the new linked kernel
| Code: | # cd /boot/grub
# grub
|
reboot.
When I get back in, the system is using the wrong kernel (2.6.21-gentoo-r3 instead of 2.6.22-gentoo-r5)
| Code: | # uname -r
2.6.21-gentoo-r3
|
Anyone have any ideas for what I am messing up? |

Before mounting /boot, can you take a look at the directory and post the contain.
Maybe you have already something the false /boot.
Also, before mounting /boot, can you output the contain of mount. |

my grub.conf contains:
| Code: | # nano /boot/grub/grub.conf
GNU nano 2.0.6 File: /boot/grub/grub.conf
default 0
timeout 30
splashimage=(hd1,0)/boot/grub/splash.xpm.gz
title=Gentoo Linux
root (hd1,1)
kernel vmlinuz real_root=/dev/hda8 udev
# Only in case you want to dual-boot
title=Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1 |
In this case, using kernel vmlinuz real_root=/dev/hda8 udev,
vmlinuz = a link (vmlinuz -> vmlinuz-2.6.22-gentoo-r5)
the link was automagically created by make install after it copied in vmlinuz-2.6.22-gentoo-r5 from /usr/src/linux/arch/i386/boot/bzImage |

| Yeah you are right on that, but what is the contain of /boot before mounting /boot from elsewhere... |

Hi
Yes d2_racing is right about that. I think you did the kernel install without
mounting the boot partition. So the mountpoint /boot is containing the
vmlinuz-2.6.22-gentoo-r5.
But the grub is pointing on (hd1.1) and this is where it finds the 2.6.21-gentoo-r3.
Mount /dev/hdb2 on /mnt or any other mount point, and you will find that this
contains the kernel 2.6.21-gentoo-r3.
Then you can get the nvidia driver to play 
EDIT: But you have to fix this /boot issue first  |

ok, now I feel silly.
I had both grub and lilo emerged, and I was configuring grub after the kernel changes, while the system was actually using lilo
I un emerged grub, configured lilo, and all is good now
Thanks for your patience guys! |
