I get the following error on booting
Unknown interrupt or fault at EIP 00000060 c0100295 00000294
which repeats continuously until it reboots a while later.
I've read here

that it's caused by

This is because the 2.6.17-10-server kernel is compiled with HIGHMEM64G support, which requires PAE, but the Via C3 processor used on most Epias does not support PAE. You will have to use a kernel without HIGHMEM64G support (HIGHMEM4G will work, as will NOHIGHMEM).
The same problem occurs on certain Pentium M CPUs. Most other CPUs since Pentium Pro support PAE.
I'm not that familiar with Ubuntu server; maybe someone else can let you know if there's another kernel available in the installer if the above is not sufficient help. Failing that, you should be able to install using the "alternate" rather than "server" CD.

However that doesn't appear to be an option for me.
I don't understand why no-one else has mentioned this? Is there a solution?
