[Gllug] DVD`s supporting DMA?

Yes :)

Sounds like you need to adapt your startup scripts.

# Mount /proc, so that vgscan and friends can use it, and /tmp, for locking.
mount /proc
mount /tmp

# Create the device-mapper device nodes.
/sbin/devmap_mknod.sh

# Ignore locking failures and make device nodes.

# Scan for volume groups.
/sbin/vgscan --ignorelockingfailure --mknodes
/sbin/vgchange -ay --ignorelockingfailure


does a perfectly good job for me.

(If your root filesystem is LVMed, you'll need to do something similar
both in your initrd and early in your post-initrd boot scripts.)
