Bug#528477: mdadm: Freshly installed 5.0.0 system unbootable, "/dev/md2 does not exist, dropping to shell"...

Package: mdadm
Version: 2.6.9-3
Severity: critical
Justification: breaks the whole system


This is a freshly installed system off of a Debian 5.0 NetInst CD burned
around 200902xx.

I've attached the output from the bug script.

Basically, the system sits for 180 seconds for the root to become available
in the initramfs and then fails.  However, if I simply manually run the
/scripts/local-top/mdadm script with sh -x, it succeeds in assembling the
arrays, I exit the busybox shell, and the system boots normally.

I looked at the script and various config files and it looks normal to me.
I really don't know what is causing this.

Again, this was a freshly installed system.  I also note that though you
probably won't see evidence of it here, the md4 array lost its sda1 member
after that first boot, and I had to manually add it back in.  I don't know
what the problem with that, but it's no longer an issue.
