I have nearly the same issue here. I just did a fresh install from the current livecd (which booted fine), but when booting from the hard disk, I get the same "BUG: INT 14: CR2 ff..." type message. The message appears nearly instantly after the kernel has started, so something very early in initialization is triggering it.
If I delete the initrd line from the grub entry and specify the root partition by hand, then the kernel is able to boot all the way to a fully working userspace.
I've never tried any other Jaunty kernels other than 2.6.28-4 on this system, so I don't know if it's a regression from 28-3 for me or not.
