I did run preupgrade to upgrade my Fedora 16(x64) to Fedora 17. And it seemed to work fine. So I got the new gimp 2.8, gcc 4.7.0 and so on. But the system keeps using the old kernel from fc16. Uname -a gives me:

Linux localhost.localdomain 3.3.6-3.fc16.x86_64 #1 SMP Wed May 16 21:43:01 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

The system downloaded the new kernel, so I got

/boot/vmlinuz-3.3.7-1.fc17.x86_64
/boot/System.map-3.3.7-1.fc17.x86_64
/boot/initramfs-3.3.7-1.fc17.x86_64.img
/boot/config-3.3.7-1.fc17.x86_64

But the system keeps using the old kernel from fc16.

If i look at my /boot/grub2/grub.cfg file, it looks like this:

#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub2-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#

if [ -s $prefix/grubenv ]; then
  load_env
fi
set default="0"
if [ "${prev_saved_entry}" ]; then
  set saved_entry="${prev_saved_entry}"
  save_env saved_entry
  set prev_saved_entry=
  save_env prev_saved_entry
  set boot_once=true
fi

function savedefault {
  if [ -z "${boot_once}" ]; then
    saved_entry="${chosen}"
    save_env saved_entry
  fi
}

function load_video {
  insmod vbe
  insmod vga
  insmod video_bochs
  insmod video_cirrus
}

set timeout=5

Anyone got a clue about why it still only references the fc16 kernel, and how I can upgrade it.

My system is using raid1 on 2 disks, but /boot is not using raid. Mount for /boot is:

/dev/sda2 on /boot type ext2 (rw,relatime,seclabel,user_xattr,acl,barrier=1)

And / (The only other filesystem I have) is mounted as

/dev/md0 on / type ext4 (rw,relatime,seclabel,user_xattr,acl,barrier=1,data=ordered)
