I think it as http://wiki.debian.org/DebianInstaller/Today states: Current issues * [27 Jul 06] Root on software raid installs are broken in testing; you need the initramfs-tools and mdadm packages from unstable to boot.and then I get busybox shell from initramfs.I'm curious if it is possible to replace initramfs within initramfs ...
I redid the install with root of software raid and no LVM and it worked fine, so my problem seems LVM-related.
