LiveCD has no SMP support

Bug Description

1. Boot the PC Dapper Drake LiveCD on an SMP system.
2. Do "cat /proc/cpuinfo".

Current result: /proc/cpuinfo has information about only one CPU.

Expected result: /proc/cpuinfo should contain information about all CPUs.

Note that this isn't really just about what's seen in /proc/cpuinfo, that's just
a simple way of verifying whether the system uses SMP. I would like to have SMP
support on the LiveCDs.

I did say it needed to be agains the "ubuntu-live" package :)

Matt, are you sure that the fix for bug 8096 covers the Live CD?

I'll interpret the lack of response to my question as "no, bug 8096 doesn't cover the Live CD".

Since it doesn't, this isn't a duplicate, so I've removed the duplicate mark.

This has been fixed with the new linux-image infrastructure where the linux-image-generic (which is used on the desktop CD) supports SMP.

Changed in casper:

Previously the LiveCD had an i386 kernel with no SMP support. There was an i686 kernel with dynamic SMP support, but that kernel wasn't used for the LiveCDs.

Just for clarity, does the "generic" thing mean that there's now one kernel for all x86 archs (i386 and others) that support SMP on SMP systems?
