On my Phenom it loads and looks good until I try to log onto the wireless
network, at which point is merely locks up - solid.
On my Gateway 5220 it boots, brings up the desktop and then, once it looks
as if the OS has loaded and all is stable, it reboots.

The experience can vary substantially with Ubuntu, depending on the hardware
drivers used for your wireless, and other devices. If you search through
the Linux kernel bug reports, there are many, you might find some related
to your hardware drivers.
I have had flakey wireless in Ubuntu depending on the kernel version, so I
would boot with the previous kernel for a while. In fact one version was
completely unusable. I also had a problem with another system after an
upgrade.
I have had problems over the last 2 Ubuntu releases with:
1. webcams (uvc driver being too old in Ubuntu) which meant I needed to
build the module myself from what was at the time an svn trunk). Most
people wouldn't go through that trouble, or know what to do.
2. wireless (hit or miss with some kernels, and "supported" devices)
3. NetworkManager (it's one of the most hated applications in Ubuntu/GNOME
land if you search google). It works for some people, but it depends on
the hardware. I have examined the code for an earlier version and I
believe it's overly complex. The interface is very poorly designed. I
ended up writing some of the scripts manually and I use:
sudo /etc/init.d/networking restart
4. Hardware accelerated OpenGL - the Ubuntu restricted driver manager tried
to use a newer driver for the nvidia card than my old hardware supported,
which resulted in black screens when I did a cold boot.
5. Skype for a while was causing what seemed to be kernel corruption, due to
some BSD socket compatibility bugs in the kernel. There is a dmesg report
whenever it's used and it states:
"[ 83.322531] process `skype' is using obsolete setsockopt SO_BSDCOMPAT"
The problems with skype went away when update manager listed a kernel
upgrade that had a fix for the BSD socket compatibility from what I recall.
So, you will probably get a lot of "it works for me" responses. It probably
does work for those people, but they have different hardware. As I
mentioned, if you search the kernel bug reports, and perhaps the Ubuntu bug
database, there are probably other people experiencing these same problems
too. It might not hurt to report the problems you experience based on the
hardware information from dmesg, lspci, and lsusb.
So, I personally doubt it's the LiveCD that's the problem. You should
checksum the .iso to verify it before writing the image to a CD-R or other
media. Based on my experience these are probably legitimate bugs in
Ubuntu.
