Comment 1 for bug 40825

I have a similar problem with a Sony Vaio. The model is PCG-505TX.

I'm presented with the boot options screen, and choose "Start Xubuntu". usplash comes up, but it gets stuck "mounting the root partition". The hard disk clicks periodically for about 10 seconds, and then I get dropped into a Busybox shell.

I think it could be because the CD drive is connected through a PCMCIA card. Perhaps those modules need to be loaded first?

Using an old Hoary Hedgehog beta CD instead works fine.
