Title:
  gave up waiting for root device (temporary, intermittent)

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  My Lucid installation sometimes fails to boot, dropping me instead
  into a BusyBox shell.  The error message looks like this:

  Gave up wiating for root device.  Common problems:
   - Boot args (cat /proc/cmdline)
     - check rootdelay= (did the system wait long enough?)
     - check root= (did the system wait for the right device?)
   - missing modules (cat /proc/modules; ls /dev)
  ALERT! /dev/disk/by-uuid/01234567-89ab-cdef-0123-456789abcdef does not exist. Dropping to a shell!
  BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash)
  Enter 'help' for a list of built-in commands.
  (initramfs) _

  My root= line contains the correct uuid.  (I masked it in the error
  message above.)

  Adding a rootdelay= of a couple minutes seems to make it fail less
  often.  This is not a viable solution, because a couple minutes is way
  to long to have to wait, because it doesn't always help, and because
  booting used to work just fine with no wait.

  If I wait a few minutes and type 'exit' at the (initramfs) prompt, the
  system boots.  Sometimes I have to try this a few times before it
  works.

  This bug is distinct from bug 360378, because in my case, the system
  is able to boot if I wait long enough.  (Note the comments in bug
  360378 stating that rootdelay doesn't help there.)

  The problem is clearly not because my disk is taking too long to
  become ready.  My root, /boot, and boot sector are all on the same
  disk.  If the disk wasn't ready, the system would not have been able
  to load GRUB or reach the BusyBox shell.

  This seems to be a regression.  My system booted consistently in early
  Intrepid kernels and in releases earlier than Intrepid.  The problem
  first showed up late in the Intrepid release cycle, presumably after a
  kernel upgrade.

  I was using GRUB 1 when the problem first appeared.  It still exists after upgrading to GRUB 2.
