I was trying to install a new lenny system over an existing old-stable
system

The computer has two disk drives used for a Raid1 configuration
MD0 is a small boot partition
MD1 is a LVM with four partitions (/ /home /var /chroot)

I tried both lenny beta-2 disk and the weekly snapshot. (The beta-2
wouldn't boot on my machine so I went to the snapshot disk)

When I selected the manual partition option, the partitioner would hang
at 52% and not present the partition map of the system. Pressing 'F4'
showed a detail screen that had both the raid and LVM partitions
recognized.

The Stable install disk worked fine.
      

It's a little bit strange that this happens with both Lenny beta2 and
the weekly snapshot.  The weekly snapshot should contain the changes
that made the installer detect both previous RAID and LVM devices during
startup but those changes are not present in the beta2 CD.

Let's focus on the weekly snapshot for now.  Does the installer
completely hang or can you switch to other Linux consoles (through
Alt+F2 for example)?

If you can, could you please give us the output of the following
command:
  $ ps | grep partman
  

11605 root   1672   udpkg --configure --force-configure partman-base
11606 root   1808   /bin/sh /var/lib/dpkg/info/partman-base.postinst conf
11607 root   1812   /bin/sh /bin/partman
11719 root   1812   /bin/sh -e /lib/p;artman/init.d/35dump

  $ cat /proc/mdstat
  

md1 : active raid1 hdc5[0] hdb5[0]
          60018688 blocks [2/2] [UU]

md2 : active raid1 hdb1[0] hdc1[1]
         32000 blocks [2/2] [UU]

unused devices: <none>

  $ pvs
  

PV         VG    Fmt    Attr    PSize    PFree
/dev/md1   VG1   lvm2   a-      57.23G   27.23G

If any of these commands hang, the problem is probably kernel related.

Cheers,
  

Assuming that I copied correctly from my screen. I don't know any way
to copy off of a machine in mid-install
