Package: mdadm
Version: 2.5.2-7
Severity: critical
Tha actual mdadm in testing makes the whole system to unbootable if on
raid slice is on the end of a disk. (In some cases)

- ------------------
Please note that I had to run the raid in degraded mode as /dev/hdc3
cannot be in the array (See below).
When I do a "mdadm --assemble --scan --auto=yes" (as done in
/etc/init.d/mdadm-raid) then I get the following error:
- ---

mdadm: WARNING /dev/hdc3 and /dev/hdc appear to have very similar superblocks.
If they are really different, please --zero the superblock on one
If they are the same, please remove one from the list.
- ---
Cleaning the superblock of /dev/hdc also clean the one of /dev/hdc3 and
so leaving the raid in a degraded state. But at least I can now boot the
system after running the md0 by hand.
Note that the partition /dev/hdd3 is also at the end of the disk but do
not make problemes.
This is a very critical bug and should be fixed in etch (I think, this
is release critical!!!)
