dmraid and dm-raid45 weirdness...

Hi,
I have a nForce4 board that has an additional sil3114 controller on it

I have the following setup:

nForce4 controller:
2x 80GB in RAID1
2x 300GB in RAID1

Sil3114 controller:
3x 250GB in raid5

The distro is Mandriva 2006 x86_64

Mu kernel is a 2.6.17.9 based kernel, with Con Kolivas -ck1 patch and 
obviously this patch:
http://people.redhat.com/~heinzm/sw/dm/dm-raid45/dm-raid45-2.6.17.6-2006731a.patch.bz2

[root@tmb ~]# dmraid -V
dmraid version:         1.0.0.rc11 (2006.05.15)
dmraid library version: 1.0.0.rc11 (2006.05.15)
device-mapper version:  4.6.0


now at boot the initrd does:

#!/bin/nash

echo "Loading dm-mod.ko module"
insmod /lib/dm-mod.ko
echo "Loading dm-log.ko module"
insmod /lib/dm-log.ko
echo "Loading dm-mirror.ko module"
insmod /lib/dm-mirror.ko
echo "Loading scsi_mod.ko module"
insmod /lib/scsi_mod.ko
echo "Loading sd_mod.ko module"

insmod /lib/dm-mem-cache.ko
echo "Loading xor.ko module"
insmod /lib/xor.ko
echo "Loading dm-raid45.ko module"
insmod /lib/dm-raid45.ko
echo Mounting /proc filesystem

echo Mounting sysfs

echo Creating device files
mountdev size=32M,mode=0755
echo -n /sbin/hotplug > /proc/sys/kernel/hotplug
mkdir /dev/.udevdb
mkdevices /dev
echo Making device-mapper control node
mkdmnod
echo Activating device-mapper raid devices
dmraid -ay -i
resume
echo Mounting root filesystem /dev/mapper/nvidia_eaeccaag1
mount -o defaults --ro -t ext3 /dev/mapper/nvidia_eaeccaag1 /sysroot
echo Switching to new root
switchroot --movedev /sysroot
echo Initrd finished



and the raid sets on the nVidia controller gets detected and activated, 
but not the RAID5 on Sil3114

So when the kernel has booted and the system is up I have to log in as 
root and simply do:

dmraid -ay

and the RAID5 set is detected, activated, and I can mount it and use it 
without problem...

Any idea why it wont get activated at boot??
