Public bug reported:

32 bit Edgy beta.

bootchart: http://librarian.launchpad.net/4918059/edgy-20061021-1.png

One 160gb drive
 Partitions:
   * 1gig swap
   * 20gig root (ext3)
   * 20gig /home (ext3)
   * rest a data (no OS files) partition (vfat)

Two 250gb drives
   * one partion, in RAID1 array with mdadm (just used for data (no OS files), 
ext3)
   
I think I have an unconventional setup with my RAID array. I first created this 
array in Dapper. When I moved to Edgy, I did a fresh install from CD. After I 
had Edgy installed, I couldn't get my array to be assembled on boot, so after 
every boot, I would have to run this to get access to my data:

sudo mknod -m 0660 /dev/md0 b 9 0 && sudo mdadm --assemble /dev/md0
--scan && sudo mount /dev/md0 /raid-data/

mdadm.conf:
   DEVICE partitions
   ARRAY /dev/md0 level=raid1 num-devices=2 
UUID=3dcc3d57:4499d301:a27ac102:cf8ea623

Every time I boot, grub loaded & booted to the splash. The progress bar
would fill up maybe 5 millimeters then not go any further for about 5
seconds. After 5 seconds, it would go to a blank screen with a flashing
underline in the top left corner.

It would stay at this point for roughly 4 minutes. Once this blank
screen disappeared, the system continues to boot to the login screen.
Pressing Ctrl+C or Ctrl+D has no effect.

If you look at the bootchart above, mdadm and a subprocess md seem to be
running A LOT.

Because I am not a developer, I cannot give any technical information on
this bug, apart from that a 5 minute boot time is very annoying.
