Lenny upgrade: Can't mount mdadm RAID drive under kernel 2.6.26

[S D <sundimi@yahoo.com>]

Hi,

Just finished "dist-upgrade" to lenny from "etch". It appears that after the upgrade the system can no longer assemble and mount mdadm RAID drives under the etch kernel 2.6.26. I still can assemle and mount my mdadm RAID drives under the kernel 2.6.18 from etch.

Here's some relevant info: 
 
Before the upgrade I had 3 mdadm RAID drives as follows, the system was working fine:
/dev/md1 was mounted as /boot(AID1)
/dev/md2 was mounted as /root (RAID5)
/dev/md3 was mounted as /swap (RAID5)

# cat /etc/mdadm/mdadm.conf
ARRAY /dev/md1 level=raid1 num-devices=3 UUID=bdf8a211:fcf6d2af:d7771298:fac716d3
   devices=/dev/sda1,/dev/sdb1,/dev/sdc1
ARRAY /dev/md2 level=raid5 num-devices=3 UUID=2ed75bfb:aed804cd:7cc7e04b:e56f1452
   devices=/dev/sda2,/dev/sdb2,/dev/sdc2
ARRAY /dev/md3 level=raid5 num-devices=3 UUID=3232181c:698319a1:67aa3321:ae8fa7a3
   devices=/dev/sda3,/dev/sdb3,/dev/sdc3
MAILADDR root



The following is what I see on the screen while booting the system under kernel 2.6.26 before it drop into BusyBox. Note the system appears to be able to assemble some mysterious /dev/md0 out of nowhere, when I should've only had /dev/md1, /dev/md2, /dev/md3:

Any ideas? Thanks
