i've squeeze and lenny installed and squeeze as a production system now.
Recently installed grub2 (1.98) on squeeze on the MBR of hd0.
Evereting goes well but i can't  boot lenny.
The lenny file system partitions are for /boot ext3 and all others ext4.
When i try to boot lenny i have this error message:  exit_fill_super:extents
feature note enabled this filesystem, use tunefs
So can't mount /dev on /root/dev, etc.....
    

does update-grub produce any error. post the output of update-grub here.

  

grub.cfg:
.../...
menuentry "Lenny, kernel 2.6.28_mm01 (on /dev/sdc6)" {
    insmod ext2
    

                  ~~~~misspell?


  

    set root='(hd2,4)'
    search --no-floppy --fs-uuid --set f26b56c1-4550-4815-b7bf-e5f114c6f9e4
    linux /vmlinuz-2.6.28 root=/dev/sdc6 rootfstype=ext4 ro quiet vga=788
    initrd /initrd.img-2.6.28
..../...

this kernel is a self-compiled with of course ext4 enabled on it and had
never problems to boot before i installed grub2.

Seems ext4 not supported by grub2 ?
    

a simple "grub2 ext4" query on google returns this
http://lists.gnu.org/archive/html/grub-devel/2009-10/msg00373.html

ext4 support was added since grub 1.97

  

any help would be very appreciated.

Thanks for the reply...
I know and googled about it before.
There are no error messages when i do an update-grub.
This is maybe the most important error message i can given on the boot:

exit_fill_super:extents feature note enabled this filesystem, use tunefs

set root='(hd2,4)' or set root='(hd2,5)' (count from 0 or 1) didn't change anything.

The root is on hd0 and partition 5 = first logical ext4 and /boot is a separated ext3 partition.

In the past grub legacy booted without any problem with lenny.
