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.

Yes, if I do  ls "/dev/sda8" -l
I get:
brw-r----- 1 root disk 8, 8 2008-01-03 19:39 /dev/sda8

This works perfectly fine. However, I do not see your point.

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 ?
