[linux-lvm] ioctl: error adding target to table, unable to mount lvm2 device nodes

This problem happened after switching root filesystem from
a debian lenny install to debian lenny install.
The raid is clean and has been correctly shutdown and re-run.
Now it will not mount my raid6 lvm2 device nodes at all,
but it shows them just fine.
With a new compiled kernel from kernel.org 2.6.30 and
lvm2,dmsetup from lenny repos i keep getting:
# vgchange -a y
I have some special raid6 setup so i think i can only use 2.6.30
(did echo raid6 into /sys in 2.6.30 to reshape to raid6 from raid5),
assembly seemingly fails on 2.6.26-2
here is the error i keep getting when trying to vgchange -a y
which is probably the reason that i cannot mount my device
nodes as xfs fs?
device-mapper ioctl: error adding target to table
table: device 9:0 too small for target
table: 253:11: linear: dm-linear Device lookup failed
device-mapper: reload ioctl failed: Invalid argument
I have everything compiled into the kernel, also DM, not as module.
but it did say:
12 logical volume(s) in volume group st1500 now active
and i can see them in /dev/mapper
if i tried to mount each of them it said:
mount: you must specify the filesystem type
or some other weird error message
i do have xfs in my kernel and can mount other xfs filesystems
but all my dm filesystems fail for some reason
Here is my config
root at mlap:~/mfs# grep CONFIG_DM .config
CONFIG_DMI=y
# CONFIG_DM_DEBUG is not set
CONFIG_DM_CRYPT=y
# CONFIG_DM_SNAPSHOT is not set

CONFIG_MD_RAID456=y
CONFIG_MD_RAID6_PQ=y
# CONFIG_MD_MULTIPATH is not set
CONFIG_MD_FAULTY=y
# CONFIG_MDIO_BITBANG is not set
Any ideas what I am missing ?
I have now tried compiling them all as modules as well into an initramfs
and my mdadm assembles fine and i can see the volumes in vgs and lvs
mdadm is active on the raid, 10 of 10 disks are up and
/dev/mapper/st1500-bigdaddy exists, i just cannot mount it,
i could do this before kernel and system upgrade
(i use an other lenny install now, but i updated udev,dmsetup,
cryptsetup,lvm2 to most recent versions on it)

I tried with dm and md as a module using initramfs now also without luck
and upgrading/downgrading udev,dmsetup,cryptsetup,lvm2 to
lenny,testing,unstable (all at once back and forth) to see if that helped
also i tried a kernel option i found on the net something like
DM_IOCTL_V4=y
but the kernel config just deleted it.
cannot seem to get it to work, tried compiling the kernel a few times also.

mount: you must specify the filesystem type
why this? I have xfs on it, but if i try hexdumping some
start bytes of the device node i just get 0's where i
usually would see XFSB?
