SubjectRAID1 + LVM not detected during boot on 2.6.9
I've installed one machine (Fedora Core 3 distro) with /boot on  RAID1 
device (md0) and all other filesystems on LVM volumes located on another
RAID1 device (md1). There was only one volume group, with couple of
volumes for file systems (one of them was root file system).

The installation went fine, however when I try to reboot machine, Linux
kernel is unable to detect LVM volumes, and panics since it can't find
root file system. I see messages saying that it is searching for LVM
volumes, but it dosn't find any.

If I boot into rescue mode from CD (also 2.6.9 kernel), and let Fedora
installer search for existing installations, all volumes are found and I
can mount root file system.

At first I suspected that I was missing some modules from initrd image,
and attempted to recreate it by hand. However that hasn't worked (I've
attached mkinitrd -v output). It seems that all needed modules and
config files are present in initrd image (SCSI, RAID, DM, and ext3 file
system).

I do remember having this very same setup working on kernel 2.6.5.
