Thanks for the reply but not sure what you mean.

sd_mod.ko is a module and it has been in initrd all the time since long 
time ago.

It used to work in that way so I assume that is not the root cause.


I've examined initrd-2.6.23.15-137.fc8.img which was an gzip cpio image, 
and found init script, and there are lines,

>> mkblkdevs
>> mdadm -As --auto=yes --run /dev/md0

so maybe the right question would be,

Why "mdadm -As --auto=yes --run /dev/md0" fails to detect md0 while 
"/sbin/mdadm -Ac partition -m 0 /dev/md0" succeeds ?
