Hi Patrick DUPRE!

I do not understand, I still cannot boot on the new kernel:

This is my grub.conf:

I cannot find "boot=" in the grub manual.  I do see it referenced but
unused in my Fedora grub.conf:

# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,2)
#          kernel /boot/vmlinuz-version ro root=/dev/sda3
#          initrd /boot/initrd-version.img

Note that the last line is commented out!  Perhaps you should do the same.
I also tried this option since it was originally commented, but I though that if you have several partition with the same label "/" on 2 different
drives, it could prevent any confusion.

title Fedora (
         root (hd0,7)
#        kernel /boot/vmlinuz- ro root=LABEL=/ rhgb quiet
         kernel /boot/vmlinuz- ro root=/dev/sda8 rhgb quiet
         initrd /boot/initrd-

I note with interest that you comment out a line that should work?
The errors you mention at the end would suggest that if you browse to
"/dev/sda8"/boot you would not find  kernel
Yes, if I do  ls "/dev/sda8" -l
I get:
brw-r----- 1 root disk 8, 8 2008-01-03 19:39 /dev/sda8

/boot/vmlinuz-  To find out, boot into a working
linux partition, make a directory in /media called sda8 (humm - can
you boot to an extended partition??) and then mount using mount -t
ext3 /dev/sda8 /media/sda8.  Then become root and browse to the disk
using cd /media/sda8/boot (or nautilus as root) and look for  kernel
This works perfectly fine. However, I do not see your point.

title Fedora (2.6.21-1.3194.fc7)
         root (hd0,7)
         kernel /boot/vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/sda8 rhgb
quiet selinux=0
         initrd /boot/initrd-2.6.21-1.3194.fc7.img

I have not problem to boot on: 2.6.21-1.3194.fc7
With the new kernel, if I put:
kernel /boot/vmlinuz- ro root=LABEL=/ rhgb quiet

if fails because it try to boot on a /dev/sdb, so I force it to boot on
/dev/sda8, but I get:

Do you have "root (hd0,7)" in the stanza?  I guess if you do I wonder
what gparted gets (using device sda) if you issue the "print" command.
I also wonder if you can boot from this partition if it is extended.
I Do not see your point. gparted does not seem to have any problem with
the partitions.
sda8 is a logical partition of an extented one sda2.
Why would it be OK with the kernel 2.6.21 and not with the 2.6.23 ?

setuproot: moving /dev failed No such file or directory
setuproot: error mounting /proc
setuproot: error mounting /sys

In what these 2 kernels are so different ?
