Title:
  "Search" line causes kernel panic on fresh 10.10 install

Status in grub2 package in Ubuntu:
  Incomplete

  Steps to Reproduce:
  1. Download and burn Ubuntu Maverick Beta. Do the checksum and CD Integrity checks to make sure the disk isn't corrupted.
  [These steps may or may not be relevant]
  2. Boot from the CD, and when prompted, use "Try Ubuntu"
  3. Set up a wireless connection to the internet.
  4. Once the connection is established, double click "Install Ubuntu 10.10" to begin the installation procedure.
  5. Select the default values until reaching "Partitioning"
  [Probably where something odd happens]
  6. Choose a custom partitioning scheme.
  7. Edit /dev/sda2, set it as an ext2 /boot partition. Format it.
  8. Edit /dev/sda3, set it as an ext4 / partition. Format it.
  9. Click next and choose the defaults for the rest of the installation.
  10. Once the installation finishes, restart the computer and remove the CD.
  11. When the GRUB bootloader comes up, select the newly installed Ubuntu 10.10.

  What should happen:
  Since this is a fresh install of Ubuntu, there shouldn't be any problems booting it after the install. After all, there hasn't been an opportunity to screw around with anything.

  What happens:
  Right after selecting Ubuntu from the GRUB menu, a kernel panic appears and the Caps/Scroll lock lights start flashing. The computer does not do anything after that. When booting in recovery mode, there is more verbose output. Here's the output that results from that:

  [0.761431] VFS: Cannot open root device "UUID=3f45a729-2066-4d4f-ae80-3cb2a7c6c4f7" or unknown-block(0,0)
  [0.761491] Please append a correct "root=" boot option; here are the available partitions:
  [0.761562] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
  [0.761662] Pid: 1, comm: swapper Not tainted 2.6.35-19-generic #28-Ubuntu

  [0.762185]  [<c010363e>] kernel_thread_helper+0x6/0x10

  Workaround: Right after a power-on, press shift to enter the GRUB
  menu. Highlight Ubuntu from the GRUB menu and press 'e' to edit the
  entry. Navigate to the line that starts with "search --no-floppy --fs-
  uuid --set ..." and delete that line. Press Ctrl+x to boot with the
  revised entry and Ubuntu should boot up normally.

  Other information:
  The first time I tried installing 10.10, I selected btrfs as the root partition filesystem to try it out. I got a similar error message, except with "UUID=..." replaced with "root=/dev/sda3". So it looks like the underlying problem is still the same. I figured that btrfs was a beta filesystem and that might be causing problems, so I installed again using ext4 as the root filesystem, and got the error output above.

  I also haven't been able to find any similar reports of this so my system might somehow be an exception situation. But I can't imagine why, and someone new to Ubuntu might not like being greeted with a kernel panic on their first boot. So it would be really nice to figure out what the cause of this might be. Thanks!
