md boot error messages


I have just upgraded from mandrake 10.0 community to 10.1 official (2.6.3 to 2.6.8.1 kernel). i am having some strange error messages on boot relating to my md raid1 configuration. They're not critical (I think) as eveything appears to work but I would like to know what they mean and why they are occuring.

My hardware configuration includes 2 disks (hda and hde) partitioned each as partition 2 (swap), 3 (/), and 4 (/home). hda is on a nvidia controller and also has partition 1 set as /boot. hde is on a iteraid controller and requires the it8212 module loaded to use it.

My kernels are compiled with the it8212 in it and raid1 as a module. The boot image is loaded with the raid1 module as well as the related ext3, and scsi modules (for other drives).

It would seem to me that mdadm is running very early in the boot process and either raid1 or perhaps it8212 has not yet been loaded so it tries to assemble the arrays and can't and then dissambles then, then appears to load the above modules and reassembles them. I'm also interested in the error message I get during the interactive boot process which appears to do the same thing i.e.
:swapon /dev/md2 - invalid device
but it then seems to assemble /dev/md2 and does in-fact mount it for swap.

I have tried using the --preload= option in mkinitrd for both the raid1 and it8212 modules (in this instance I compiled the it8212 as a module) but this didn't change anything. As a matter of interest but probably unrelated I am also having problems with devfs conflicting with udev in case this is related. Any help or pointers is appreciated. Details below:

this is my my /etc/mdadm.conf
Code:
DEVICE /dev/hda2 /dev/hde2
DEVICE /dev/hda3 /dev/hde3
DEVICE /dev/hda4 /dev/hde4
ARRAY /dev/md2 devices=/dev/hda2,/dev/hde2
ARRAY /dev/md3 devices=/dev/hda3,/dev/hde3
ARRAY /dev/md4 devices=/dev/hda4,/dev/hde4

I get the following interesting boot messages in dmesg
