Title:
  Boot fails with busybox prompt using LSI Logic / Symbios Logic
  SAS1068E PCI-Express Fusion-MPT SAS [1000:0058] (rev 08) SAS Disk
  Controller

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Upon installation of 10.04 32/64bit and 10.10 64bit, to the SAS
  drives, Ubuntu boots into busybox.

  The following SAS controller is still not properly supported in Karmic, Lucid or Maverick:
  LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS [1000:0058] (rev 08)
  Module: mptsas

  The Precision WorkStation T7500 was purchased from Dell with Red Hat
  5.3 64bit preinstalled.

  We have tested the "rootdelay=60" boot option (tip found in one of the
  similar bugs) which did not work.

  We have tested using the Maverick Daily from 23/07/2010 as well as
  2.6.35 RC6 from the mainline PPA.

  The symptom we are seeing is being booted into busybox when booting
  Ubuntu from the SAS drive. Booting into recovery mode brings him to an
  initramfs prompt. Booting from a SATA drive seems to works. The BIOS
  version is A05, the latest.

  Similar bugs seem to confirm the issue with this controller:

  We went through the following after installing Lucid 64-bit:
  1) Boot from LiveCD
  2) Mount drive with installation
  3) Mount proc dev and sys
  $ sudo -s
  # mount -o bind /proc /media/external_drive/proc
  # mount -o bind /dev /media/external_drive/dev
  # mount -o bind /sys /media/external_drive/sys
  4) chroot into the external drive
  # chroot /media/external_drive/
  5) upgrade your system
  # sudo apt-get -y update; sudo apt-get -y upgrade; sudo apt-get -y dist-upgrade

  6) (Optional) - Just to play it safe, we tried the latest kernel available to see if the issue was fixed.
