[Bug 1286047] Re: Ubuntu 13.10 not booting on hardware RAID

[Hag K]

I can confirm that the initially reported problem does not occur once
legacy BIOS support was disabled.

Within UEFI/ BIOS user interface I changed the Compatibility Support
Module (CSM) to "UEFI only" to basically switch off the legacy BIOS
support. After that, only the UEFI compatible installer was available
when booting the Ubuntu 13.10 installer from the USB Stick. After the
installation was successfully finished the subsequent reboot then
correctly showed the Grub loader for a brief moment and then started up
Ubuntu 13.10.

However, the Ubuntu startup fails, at least once, at a different stage
than initially reported with this bug, after having overcome the problem
discussed above. I'll attach the description of that subsequently
encountered problem and it would be great if you could give me your
opinion.

Title:
  Ubuntu 13.10 not booting on hardware RAID

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce with Ubuntu 13.10:

  1. Setup the adaptec RAID controller to use ANY of the RAID modes
  2. Install Ubuntu 13.10 (in my case from USB) by using either classic partitioning or LVM
  -> Observe that the installer correctly finds the RAID disk and the installation process finishes successfully
  3. Boot the system
  -> Bug: System does not boot into the newly installed Ubuntu 13.10

  Hardware:
  - ASUS H87I-PLUS Motherboard with latest UEFI/BIOS update
  - Adaptec RAID 6405 Controller

  Note the issue reported here is not encountered with Ubuntu 14.04
  daily build (downloaded 27/02/2014). So it appears that Grub 2.02 used
  with Ubuntu 14.04 has a positive impact as it resolves the bug. I hope
  this will be another good reason to ship Grub 2.02 with Ubuntu 14.04
  LTS.
