[Bug 510571] Re: Lucid guest won't boot with acpi in virtualbox

[arand]

** Description changed:

- Lucid is unable to boot as a guest operating system in virtualbox when having acpi enabled.
- (Issue first triggered on kernel 2.6.32-11 and is present on all later versions)
+ Lucid is unable to boot as a guest operating system in VirtualBox when having acpi enabled.
+ Applies to Karmic & earlier versions of VirtualBox
  
- This seems to apply to all versions of virtualbox prior to 3.1.4 beta
- (OSE and PUEL) when booting lucid (or any other system with a newer
- kernel).
+ ------
  
- The problem has been fixed upstream.
+ TEST CASE:
+ 0.1 Boot a pre-Lucid release of ubuntu
+ 0.2 Install VirtualBox
+ 1. Create a new virtual machine in VirtualBox
+ 2. Attach a Lucid liveCD (e.g. beta1) and start the virtual machine
+ * The machine is unable to boot
+ ! Expected is that the machine should be able to boot
+ 
+ Workaround:
+ Either disable acpi in the VirtualBox settings, or use acpi=off as a kernel parameter when booting.
+ 
+ Impact:
+ This affects the testing of Lucid as well as running any distributions with a newer kernel.
+ The number of affected users can be expected to increase
+ 
+ Scope:
+ Issue first triggered on kernel 2.6.32-11 in Lucid and is present on all later versions.
+ This seems to apply to all versions of VirtualBox prior to 3.1.4 beta (OSE and PUEL) when booting Lucid (or any other system with a newer kernel). That is, all versions prior to Lucid's (Karmic & Jaunty confirmed)
+ 
+ Fix:
+ Changesets r26129 (http://www.virtualbox.org/changeset/26129) and r26130 (http://www.virtualbox.org/changeset/26130) from upstream SVN fixes this bug, and testing of these through patched PPA package (https://launchpad.net/~arand/+archive/virtualbox) seems to be successful
