  disk detection is real slow with some hardware (timout shell drops)

Bug description:
  I have installed Intrepid server i386 beta on a Dell PowerEdge 600SC.
  Everything seemed to install fine but upon boot it always drops into
  the BusyBox shell. The RAID is *not* degraded. At the BusyBox prompt
  if I type 'exit' it will proceed to boot normally and both RAID1
  drives show healthy with all members. I have tried the install twice.

  This has shown to be a timeout issue with slow hardware.

  * initramfs: Default rootdelay may need to be larger and event driven
  upstart used.

  * linux: The long delay may have its cause here.

  * mdadm: As RAIDs may take minutes until they come up, but regular ones are quick, this should be handled nicely:
  * This functionality is similar to and could most easily be added with upstart events (the temporary tool) mountall:

        "NOTICE: /dev/mdX required for the root filesystem didn't get up
  within the last 10 seconds.

        We continue to wait up to a total of xxx seconds complying to the ATA spec
        before attempting to start the array degraded.
        (You can lower this timeout by setting the rootdelay= parameter.)

        <countdown> seconds to go.

        Press [ESC] to stop waiting and to enter a rescue shell.
